come back the traffic on same interface which it input

come back the traffic on same interface which it input

[Usuário do Sistema]

hello everyone, I have two ISPs in my firewall that are ADSLs lines. I
wish that all trafic input in wan1 ( ISP1 ) come back on it. but this
isn't happening because the firewall gateway is ISP2 ( wan2 ) so all
input traffic by ISP1 ( wan1 ) doesn't work because the firewall
forwards all traffic as it as your gateway wich is ISP2

for exemplo, I have a http service on this firewall and when I attempt
 access it from Internet doesn't work because it's on my ISP1.

how I can do for all input traffic on wan1 come back on it and not on
wan2 wich is the firewall gateway ??

any tips are welcome

Here is a good start for a simple implementation:

If you need to be more selective, you can use iptables markings to get
finer control:
