Hi all, Below are the config I tested and results: 1. IPTABLES -A POSTROUTING -s 192.169.10.0/255.255.255.0 -j SNAT --to-source xxx.xxx.85.113-xxx.xxx.85.115 2. IPTABLES -A POSTROUTING -s 192.169.10.0/255.255.255.0 -d xxx.xxx.85.113 -j MASQUERADE 3. IPTABLES -A POSTROUTING -s 192.169.10.0/255.255.255.0 -j MASQUERADE config 1, everything is working fine except msn and yahoo messenger voice chat. config 2, everything is working fine except msn and yahoo messenger voice chat. config 3, everything is working fine including msn and yahoo messenger voice chat, the only problem is that this configuration is not fitted to our setup. Can anybody have an idea on using config 1 and 2 with msn and yahoo messenger voice chat enable? or do you have any solution enabling similar to config 1 with all features enable? Thank you very much, Wennie
