Hi, I've a real novice when it comes to Firewalls but have a simple setup and have managed to get things working without any problems so far.
I have a few machines behind a PIX 520 sitting in a rack. At the moment. I have routed various external IP's to internal IP's on my servers.
e.g.126.96.36.199 -> 192.168.0.10 188.8.131.52 -> 192.168.0.20 184.108.40.206 -> 192.168.0.30
etc This all works fine and I've set all the ports that I need open etc. However, if I make a Web request or e-mail etc from one of the machines internally to it's self - e.g. On server 192.168.0.20 I try to look at the website on 220.127.116.11 (which is the same machine) it will not work and is blocked by the FW as the source address is the same as the destination address. So the Firewall thinks it's a Land Attack.
How do I configure the PIX520 to allow this through? Am I configured wrong as I imagine this is a common situation.
Any help/advice would be great. Bear in mind I'm in no way an expert on Cisco Pix equipment.
