Dear List!

I just want to ask you a question.I have a linux(Secure platform) gateway
server with 2 external ip address to the internet (one S/0 ADSl, second S/1
Point to Point) and one internal ip eth0 for my LAN. I need to split up the
outgoing traffic.HTTP/HTTPS want to route through the ADSL and the rest of
traffic (SMTP,POP3,FTP) through the Point to Point.Can i solve this with
Linux iptables or whatever else. Any suggestion help..

regards,

Chris
