I have a Linux gateway with 2 ISP's, <br />
<br />
(1) I want to route my VPN traffic through ISP1 and rest of the traffic through ISP2. When both ISP's are working fine.<br />
(2) I want to route my VPN traffic and all other internet traffic through ISP2 if ISP1 is down.<br />
(3) I want to route my VPN traffic and all other internet traffic through ISP1 if ISP2 is down.<br />
<br />
I have 3 NIC's<br />
eth0 - ISP1<br />
eth1 - ISP2<br />
eth2 - Local LAN<br />
<br />
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.<br />
<br />
Solution Please<br />
<br />
