2 ISP's - Linux Gateway Router
Posted on 2003-12-07
I have a Linux gateway with 2 ISP's,
(1) I want to route my VPN traffic through ISP1 and rest of the traffic through ISP2. When both ISP's are working fine.
(2) I want to route my VPN traffic and all other internet traffic through ISP2 if ISP1 is down.
(3) I want to route my VPN traffic and all other internet traffic through ISP1 if ISP2 is down.
I have 3 NIC's
eth0 - ISP1
eth1 - ISP2
eth2 - Local LAN
When the Internet traffic is changing from one ISP to the other the end user should not feel the difference both for internet traffic and VPN traffic.
