Hi I am using FreeBSD 4.10 stable (cvsupped about a month ago), and I have hit a problem with the firewall configuration and allowing a specific application to work. At the moment all sorts of things work correctly: The FreeBSD machine acts as a test-server and firewall when I'm working from home My WinXP and Apple OSX 10.3.5 desktops can see web pages, send/rcv email I use vtun to enable all 3 machines to access my corporate VPN, What is NOT working is iChatAV on the Mac. The remote person always seems to get a connection timed out error stating that they are unable to connect to 10.0.1.1 (the ip address of the mac on the INTERNAL network, rather than the fixed IP address of my DSL modem) The DSL modem thingy contains a primitive firewall, and applies NAT to the packets addressed to the external ethernet address of my FreeBSD computer. This computer then uses firewall/NAT rules to allow packets in to/out from the other two computers. I can even successfully play Quake III on-line from the Windows box, so the NAT redirection of UDP packets is working there... If anyone on the list has successfully configured this to work, I will be prepared to send you my rc.firewall and natd.conf files to see if you can help me.
