Connection time out to my own webserver from external desktop device but ok from mobile network

Hi all,

 

I am computer scientist myself but not specialized in network administration so I have some educated investigation to the weird problem I am having. Please accept my apologies for the long post and possibly bad English.

 

Setup: Rogers Ignite 250u using CGN3 modem. Web service hosted by NAS setup behind the modem. Domain hosted by external dynamic DNS services. Correct port forwarding is configured in modem. 

 

Observations:

1. From external, desktops, laptops and Windows tablets CANNOT access the website, either on wired network or on corporate WiFi. (Never tested iPad)

2. However, laptops and Windows tablets CAN access the website if they are tethering through a mobile network. 

3. From external, cellphones can always access the website, no matter it is on mobile network or on corporate WiFi. (Both Android phones and iPhones work)

4. Within the local area network, all devices can access the website. 

 

I tried using tracert to find out if it is a routing issue but I think one of the Rogers had blocked tracert/ping packets. 

 

Does anyone have any hint on solving the issue? 

 

Thanks in advnace,

Jackie

Very strange indeed. It works on my mobile phone browser but not on my desktop. Both are connected to the same router. Let me look into it

I have done something seems to be unrelated -- unblock p2p ports in the CGN3 firewall. However, those website health analysis software are able to load the site now.

I can't explain why the p2p ports are used in desktop browser.

Re: Connection time out to my own webserver from external desktop device but ok from mobile network

Jackielo it seems to be working now on both.  May I offer a suggestion? Im not against anyone using their personal home internet connection as a web server but we reached a point technologically that you can possibly find offsite hosting for free or very inexpensive.  Using your home internet for hosting may be smart but you also should be aware your internet connection stability can play a factor. If a truck crashes into a cabinet on your street it could take down your internet server and if you have an important client who needs to email you you run the risk of the email not being delivered properly or not on time.  Plus rogers service level agreement may not cover certain things that running a server 24/7 requires

Thanks for the advices. I am quite aware of the maintenance issue, so no time sensitive things are hosted in that server.
