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..
You want to use "Policy based Routing".
( http://en.wikipedia.org/wiki/Policy_based_routing )
The principle is to use iptables to set a numeric mark (-j MARK) on packets
according to you criteria (tcp destination port number, ...) and to use a
different routing tables which are selected according to this packet-marks.
