Or masquerade all traffic to the new server with firewall rules: iptables -t nat -A PREROUTING -i ethX -p tcp -m tcp --dport 143 -j DNAT --to-destination 1.1.1.1 iptables -t nat -A POSTROUTING -d 1.1.1.1/32 -p tcp -m tcp --dport 143 -j MASQUERADE ethX --> interface where connections come from 1.1.1.1 --> new server IP address Maybe smth is wrong up there, didnt tested, but I think its cool. cheers. -- x9p | PGP : 0x03B50AF5EA4C8D80 / 5135 92C1 AD36 5293 2BDF DDCC 0DFA 74AE 1524 E7EE
