Comcast Business Class server setup

Question

I have just purchased Comcast Business Class internet (CBC) for my small business and I am acustom to being able to use my own equipment. Normally to direct HTTP traffic to a server on my local LAN all I have to do is port forward 80 incoming to the correct IP. I am completely lost with CBC and my SMC router. I have tried several configurations and it seems the only configuration I have been able to get working semi-correctly is giving the server the Static IP I wish it to have and setting everything else manually.

I have read at several locations this is an easy setup. 1-1 NAT with port forwarding should do the trick. This isn't working for me at all. It does indeed direct HTTP traffic, but it only directs the traffic to my SMC router login page. The traffic never actually gets past the router.

I tried talking with Comcast Tech support and they are either unwilling, or unknowing.

I have Ubuntu 10.04 setup and have a static IP I can use. How can I get this sucker to the outside world.

Answer 1

Just want to clarify if you have port forwarding setup correctly.

Suppose the LAN IP of your router is 192.168.1.1 and that of the server is 192.168.1.100

You would setup port forwarding on the router to forward port 80 to 192.168.1.100:80 and not 192.168.1.1:80

In case you have allowed your router to be administered using your WAN interface disable that.

Answer 2

If your on the local lan you won't beable to see the website from the external IP. You can test your setup using a proxy.
