Hi all,

Im using IP tables and Im having problem. 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

masquerade also your pubilc interface going to private interface

say your public interface is eth1, private is eth0:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
