I apologize if this has been discussed before. I did search and could not find an identical issue.
I am using iptables to forward ports 80 and 100 to a system behind the firewall, 192.168.1.2 This is working. From an external IP a request for the http://www.mydomain.com site is properly forwarded. My problem is that the same request from behind the firewall is not forwarded. For example, if I am at IP 192.168.1.100 and request http://www.mydomain.com, it eventually times out. For the record, a request for an outside domain is allowed so the NAT is working. I think I must be missing a rule but I have no idea what it is. Any assistance is very much appreciated. Thanks.
