Access to my web server behind Modem

I'm Here A Lot

Hi All:

Just got setup on Rogers today after many years with Bell.  Their connection in my area is max of 5 Meg and I'm getting 100 Meg from Rogers for about the smame money - so I'm very happy so far...

I'm rather savy about computers and such, and managed to get my home network up and running with no problem, but I'm unable to access my web server.  This server is hosted on a second computer on my home network.  The modem has this computer in it's configuration so it can see it.

This server runs Apache and just servers a little content (family pictures, news, streaming cameras, etc.).  It was running fine on the DSL, but I can't seem to access it with the new modem.

I read (today) that port forwarding may fix this but I would like to hear for anyone else if they have had this problem and how to solve it. 

I have one of those new modems, not entierly sure the make or model.

Also - does anyone have a link to a manual on the modem?  I usually like to refer to one if I hae a problem.

Re: Access to my web server behind Modem

Ok, its the CGN3.

They dont really supply much documentation.. as there are sometimes a bunch of things in it.. that you CANT do... the Manufacturer makes it with say 100 features.. but the providers is the one who limits what of those are active.

Dont wan the manual to say you can do THIS, when in turn, you cant.

FIRSTLY.. the rogers modem/gateway... nor MOST routers as a whole.. USUALLY do not support what they usually call LOOPBACK.  (there are ocasionally some which do)

When you are internal... and you put in your dyndns address (or even your modem address), they TRY to go to it.  Well, it fails, as you are already INSIDE that address to begin with.

So, when trying to access the webserver, or the cameras, etc, while INSIDE your network.. you would want to use their SPECIFIC internal address. (or host name)

 

As for the OTHER settings.
Go to the ROUTER settings page (192.168.0.1 or 192.168.1.1  depending on how yours is set up).
Login with the default login 'cusadmin' and password of 'password' (unless you have changed it.. if you have not changed it, i reccomend doing so)

 

Click on basic at the top.. then port forwarding (might take a min before it goes to the port forwarding, as it finishes loading the device table on the lan setup tab)

 

you will want to add rules in there 

So make one for Calibre... public and private, put in 8080-8080 (needs a range, so you put it that way, for one port), and then the IP of where it is.  Same sort of thing for the webcam.. the regular web server, etc.

I have a web server, FTP, and a port for my media server, all set up in the CGN3, and it works perfectly fine 🙂

Well, we would need to know the model of the exact modem, to be able to help with the manual, and any further configuration 🙂

 

Now.. when you are trying to access the webserver... is this from INTERNAL? or EXTERNAL you are having problems?

(external, will require port forwarding set up).

Re: Access to my web server behind Modem

Hi:

 

Thanks for the quick reply.

 

It seems to be from both ends - but not from the server system.  When I use the IP address of the server from my other computer, or try to access the site from external (I use a DYNDSN to map my IP to my name) I get the Router sign-on.

 

I also have services running on specific ports (Calibre port 8080, Web Cam on 8081, etc).  From what I understand, these all have to be fixed in the router.

 

I will try to find the router model if I can.  I got absolutely no documentation - just a plain cardboard box that the modem came in. 

Re: Access to my web server behind Modem

Hi (again):

 

Looks like it is one of these http://www.rogers.com/web/link/modems

at least it looks like this one

 

I don't even know if the LAN ports on the back are 100 M or 1 G speed.....

Re: Access to my web server behind Modem

Hi:

 

Thanks for the detailed information. 

 

I'm now at home and I have done what you described about the port forwarding.  I set up the HTTP, Calibre, etc. and pointed them to my server IP address.  Problem is that when the router rebooted (when I saved everything), my server

got assigned a different IP address (DHCP you know...)

 

So - I set the server with a staic IP address outside of the DHCP range and then re-did all the port forwards.  And of course, rebooted the router.

 

So - now I have the ports set up and I can access the web pages from INSIDE using the IP address of the server.  I guess I'm going to have to wait until tomorrow to see if I can access from OUTSIDE.

 

I will let you know what happens.  And thanks again.

Re: Access to my web server behind Modem

Yeah, You really need to have ANY device, which you port forward to.. on a static address 🙂
(shouldnt matter IF its inside the DHCP range, as the router will pick up on the broadcast, add it to its list, then not assign it.... but it is BEST practice to put it outside).

Assuming its all correct, you should be able to access it.

 

I have done 80 for my HTTP server and it works fine... when i had an alternate one, on 8080, it did work (no longer use it).

Re: Access to my web server behind Modem

Hi:

 

Great news - everything seems to be working on the site when I access from an external computer.  My only issue is that I forgot one of the ports to be forwarded so I will add that one later.

 

Thanks again for the advice / help.

Re: Access to my web server behind Modem

No problems 😄

 

Glad you got it working.

Re: Access to my web server behind Modem

Hi everyone,

 

I appear to be in the same boat.  After many years with Bell, I too switched to Rogers Internet and am running the CSN3 router.

I read through this thread and have a very basic understanding of it and feel my issue may be the same or similar.   Sorry for my ignorance.

 

I have a Synology NAS (model DS412+) which worked great with my Bell router.

I was able to access files on the server from other computers in the house as well as video's through my smart TV.  

 

Since switching the router out, I am unable to even get into the NAS via the IP address I would type into my browser bar.  I am also unable to see and access the server files from any of the computers in the house with the exception of my Mac for whatever reason.  The server name still appears in the left side of my finder window and despite being slow, I can access files.  The PC's in the house and smart TV are unable to see the NAS.  

 

I think that this may be a port forwarding issue as well but, have no clue as to how to create rules and/or fix this issue.  

I find it odd that I can't access the server via the IP address anymore and that the files are only accessible via my Mac.  

 

On a side issue, I was never able to configure my NAS for outside access as I had "port forwarding" issues with the Bell router as well.  At least with Bell, I was able to see, access and maintain the NAS from within my home without issue.  If anyone knows how to set me up so that I can also access the NAS from external sources as well, it would be appreciated.  At this point, I'd be happy to just be able to get it up and running within my home again.  

 

I'm guessing that Rogers, Synology and Apple will all refuse to provide tech support on the issue.  

 

Any help would be appreciated.

 

Thanks,

Bob

Re: Access to my web server behind Modem

Just to confirm.. your NAS, is assigned an IP address?

 

And its in the same range as all the others in the house

(so its say 192.168.0.10 and your on 192.168.0.20, etc)

 

And its INTNERAL IP is what your trying to type in to see it?

 

Re: Access to my web server behind Modem

Hi there, yes....the NAS has a similar IP address assigned to it.  I would access the NAS settings and preferences by entering the IP into my browser and then log in.  I believe that this in an internal IP as it was provided by the manufacturer of the NAS.  Similar to a router IP no?  

 

Now, it refuses to even take me to the sign in page of the NAS.  

 

When I open a finder window, the name of the server is stil listed in the left column.  I am able to access the folders on the NAS from the finder window on my Mac but, unable to access from the other PC's within the house and on the network.  

Re: Access to my web server behind Modem

Now that I look at the IP's I guess they are a little diffrent.

 

ie)  192.168.2.20  vs 192.168.0.10 

 

Is this the issue??  

Re: Access to my web server behind Modem

Quite possibly.

If your computer IP is in the 192.168.0.x range, and the NAS is on the 192.168.2 range..

You would be best to change the IP the NAS (could temporarily do this, via changing your LOCAL IP temporarily to the same 192.168.2.x range), or change your router DHCP to work in the NAS range.

Re: Access to my web server behind Modem

rodeghiero

Okay,  

 

Okay, as it turns out, the Rogers router gave the NAS a new IP which explains why my old "bookmarked" IP for Bell was not working!!!  D'Oh!

 

I was able to figure out what the new assigned IP is and am now once again able to log into the NAS.  I am also now able to see the NAS file folders on the other comptuers and devices within my home.  Not sure if shutting down the NAS had anything to do with it or not.  

 

I really appreciate your time Gdkitty and sorry for any bother.  It seems to have resolved itself.  Thanks for your time!! 🙂

 

Regards

Re: Access to my web server behind Modem

LOL, that would do it, if you were going off an old bookmark XD

 

Glad its working now. 
In the long run, i would say its best to SET the NAS to a static address... as a reboot of the router, could cause it to get a different address the next time.

Re: Access to my web server behind Modem

Ok.. I have a similar problem but apparently just a bit different..

I am running Wamp server from my home pc. Its a clean install of Windows 7.

I have the advanced wifi hitron gateway (CGN3) and I have it bridged to my D-Link dual band DIR-826L wireless router.

On that router I have a static ip address assigned to the Windows 7 pc that is running my web server and rather than fiddle with ports just yet, I just went ahead and set the pc's lan ip to the DMZ.

 

Now, I can access the web server via another computer on the network  on its static ip (192.168.0.100)

so I know the web server functions properly...

 

I also have NO Ip dns forwarding set up with their ip updater program on my server pc keeping the dns updated with my external ip address..

 

That service says its connecting fine to their system and shows my correct external ip address. My web server obviously has a green icon, indicating it is fully online and this is confirmed by my ability to see the website I have up via a my laptop on wifi (server is on ethernet)

 

I've had this working very well at my old house, just a 30 second drive down the road but I had the cisco D3 gateway or possibly the SMC D3 at the time, I believe.

 

Any ideas or questions for me? I'm stuck... Rogers won't help me at all cause servers or anything related to dns or servers without me going through a business account...

 

Edit:... I forgot to mention, when I try to access the website via ip OR the web address, I get this message.

 

"Unable to connect

Firefox can't establish a connection to the server at myfakewebaddress.ddns.net:8080.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer's network connection.

Hello, I have port forwarding on the Advanced modem but these modem do not support External Loopback, correct? I am unable to connect to my plex server using my dyndns.tv link but can internally. Does the Rocket modem support this? The Cisco DPC3825 modem does but I wanted to use the newer ones. Thx

I'm Here A Lot

Please help!! I have my own website and can access it on my home network no problem. Trouble is when I try to access it outside home network I get nothing. My site is not visible on the net, outside of my home network. Could someone tell me how to fix this, Thanks. Modem is rogers model number CGN3

Re: Access to my web server behind Modem

Hello @myasdad,

 

Thank you for posting and welcome to the Rogers Community Forums! 🙂

 

Being able to access your web server outside of your home definitely sounds important! Rest assured you have reached the right place, we have numerous Experts that may be able to look into this and hopefully find a solution that works for you.

 

I am tagging in some of our Resident Experts @Datalink@Gdkitty, and @gp-se to provide some insight on this inquiry.

 

Cheers,

 

RogersTony 

 

 

Re: Access to my web server behind Modem

I am assuming you are running this site on one of your machines there at the house?
There are a few things which need to be done to make it visible.

When you are inside your house, you are on the same network, so its easily visible.  Problem is when you go outside your house.. there is the router/firewall in the way.

 

A) You will need to set up port forwarding.  Whatever port the webserver runs on (default is usually 80, but could be others).  In the modem settings, you will need to set it up to forward that port, both external and internal, to the IP address of the machine running the webserver.

B) whatever machine is running the webserver, you will want to set to a STATIC IP address.  This will keep it from potentially changing at any time.  Because every time it changes you would have to keep changing the port forwarding settings.
