even if you open the ports say on the forwarding.. you do need a device (either in the DMZ or forwarded to) that has those ports OPEN to be receiving something.
Say a web server for 80 or ftp on 21, awaiting connections, for it to get a response from.
But its still possible yours hasnt been updated. You should be able to call in and have them push out the latest to you.
The main advantage of that one vs the other ones.. is that as a gateway, has much better wireless vs the others. If this isnt an issue, or you use a 3rd party router in bridged or as an AP.. switching to one of the others, shouldnt be an issue. (as long as you are not on ultimate..i beleive that one is/may be a requirement.)
I have the SMC and have no issues with port forwarding on it... and have my own router just as an AP.

I think it makes sense, that while having something in the DMZ and the forwarding on, would cause a conflict.
When you put something in the DMZ.. its outside of the firewall. Pretty much, count it like, ITS assuming by default, any connections into the router, if it can.
Port forwarding, would then try to do it again.... OR.. its trying to push to an IP of a device which normally is INSIDE the firewall.. and it now outside of it.
Nice work around, for the same IP address.. 🙂 only other option would be to play around, with one in the DMZ, and the other with port forwarding.
Last i heard (havent heard otherwise) the cgn2 the forwarding DOESNT work on it 😛
Odd, that you cant do BOTH... but again.. i GUESS it makes sense.
Yes, each machine has its own seperate IP address INTERNALLY, right?
BUT... now something, lets say a game server, etc is trying to send info BACK to your house.. it only sees, ANY device from your house.. comming from ONE external IP. Its trying to send to port 12345. It hits your IP address.... now where do i go? Do i go to the one in the DMZ which is open? or do i go to the fordwarded one?
I have the SMC.. it doesnt have a set number of lines.. so not sure if there is a limit or not.
