I'm in the process of setting up a network and have run into some problems. I have two devices on my network (IP's 192.168.1.20 and 192.168.1.21) that are accessed via port 80 (non changeable). Right now, I have all traffic sent to my firewall (I only have one real IP) on port 80 forwarded to 192.168.1.20:80 and all the traffic to 81 sent to 192.168.1.21:80 via natd. The problem is, when a connection from the outside is made to 192.168.1.21, it responds by trying to open a new connection on port 80. When the outside computer connects, the firewall forwards the now-port-80 connection to 192.168.1.20, leaving no way of reaching 192.168.1.21. I've tried forwarding traffic from higher ports to internal machines (ie ssh) with success, so I can only assume that when 192.168.1.21 gets a request, in opens up a new connection, thereby losing the original :81->192.168.1.21:80 forwarding. Is there any way I can set up the firewall so that all outgoing traffic from 192.168.1.21:80 leaves the firewall on port 81?
