> 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..
You can ( must ) use 'ip route','ip rule' and tc set of instructions.
In a few words.
You create a table where store routes ( /etc/iproute2/rt_tables )
Then you can create a set of routes to be stored in this table
ip route add default via adsl table out-http
Then, assign policies ( rules ) to use the defined set of routes
depending on the type of outgoing packet ( proto, source, dest... ).
When a packet matches an assigned rule for table out-http, the routing
processes 'forget' standard routes and applies the set of routes defined
in table out-http.
This is well explained in the excelent howto http://lartc.org/
