Being able to pass traffic through the wan in the table marked with a different source IP address.

[samueljaydan]

There are 2 WAN interfaces.

WAN1 => fwmark 1
WAN2 => fwmark 2

lo998 has 2 different IP addresses. 127.0.88.1 will be used for WAN1, and 127.0.88.2 will be used for WAN2.

WAN1 => gateway => 1010.12.1
WAN1 => ip address => 10.10.12.254

WAN2 => gateway => 192.168.1.1
WAN2 => ip address => 192.168.1.3

When I run "ping -I 127.0.88.1 8.8.8.8", I want it to go through WAN1, and when I run "ping -I 127.0.88.2 8.8.8.8", I want it to go through WAN2. What should be the necessary iptables rules for this?
