Web server behind Comcast modem (Loopback issue)
I am trying to setup a web server running behind a comcast modem. We can access it from outside our office network. But, if we try to access it using global ip from local area network, it does not work. I guess loopback occurs and we cannot see it. We can access it using local ip instead of global ip.I have gone through all setting on the modem, but i cannot find any setting for loopback. Is there any way to make this work??
The firmware version on the modem is as follows.
Vendor NameNetgear
Hardware Version1.04
Firmware VersionV1.34.04
Thanks for your help in advance.

Not sure you are still looking for suggestions on this or not but your trouble is with NAT reflection. Many router/firewalls cannot do it properly. I haven't used the Netgear device, I have an older Comcast router. What we do is disable all firewalling on the Comcast device and use a software firewall called pfsense. It can be installed on a PC that has a couple of network cards in it. You can then set it up with the Comcast public IP's you have so long as the Netgear will support that. pfsense has NAT reflection built in so you can access your public IP's from inside the local network. pfsense also has some great features like bandwidth limiting by IP or protocol, IPS add-ons, lots of other cool stuff. Check out pfsense at pfsense.org.
