Hi. I have basic firewall iptables rules in my Linux gateway (NAT) and Im having some problems with the computers behind the firewall. The MSN messenger losts connection after a few minutes of login I have 3 Network interfaces, one for server network via eth0 (these have valid IPS) one for Internet via eth2 (MSN goes throug here) and one to connect the internal Net to the other two Networks (here are office computers) The Rules for each user are: sbin/iptables --table nat --append POSTROUTING -s USER_PRIVATE_IP -d 0.0.0.0/0.0.0.0 --out-interface eth2 -j MASQUERADE /sbin/iptables --table nat --append POSTROUTING -d LOCALNET --out-interface eth0 -j MASQUERADE /sbin/iptables --table nat --append POSTROUTING -d 0.0.0.0/0.0.0.0 --out-interface eth0 -j DROP /sbin/iptables --table nat --append POSTROUTING -d 0.0.0.0/0.0.0.0 --out-interface eth2 -j DROP Any suggestion about the MSN disconnection ? Thanks. Camilo. -- _____________________________________________________________________________ Cuando un Arquero dispara gratuitamente .. Tiene consigo toda su habilidad ...
