Did you set the system to do IP forwarding? In /etc/sysconfig/network, set "FORWARD_IPV4=yes"
In /etc/sysctl.conf, set "net.ipv4.ip_forward = 0" Then, you'll just need to make sure that your firewall rules are set to forward connections from inside your network to the outside. However, if you're already using your internal server to send mail out, and you're using a proxy for your web browsing, why not set up fetchmail and have your server pull down the mail to itself, and have your internal systems poll it via POP3?
