The problem I'm having is that I cannot connect to the mail server on network A (10.0.0.2) from any machine behind the NAT gateway on network B. However, any system on network B can successfully ping the gateway of Network A, as well as connect to the two HTTP servers running on the same host as the mail server (10.0.0.2). The mail server is running, since I can connect to it from the NAT box on network A (via internal address) and via public port-forwarded address from the NAT box on network B. Why can't I connect to it from behind the network B's NAT gateway, when I can connect fine to other services running on the same machine? -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
