iptables -t nat -A POSTROUTING --destination ${server2} -j SNAT --to ${server1_internal_ip} This is the last time I try to respond to you since you've been ignoring the rest. SNAT traffic from server 1 to server 2. Period. There's no magic. Put it in, then the system will magically work. Well, replace the ${}'s with the actual values first. If you even get this email, let me know cause I feel like I'm falling on deaf ears.
