Routing one LAN traffic through a specfic WAN link
What I have right now is this:
2 WAN links = WAN and OPT2
2 LAN links = LAN and OPT1
I have a specific LAN IP [192.168.1.201] that needs to go out only through OPT2 - how do I do that?
I realize it should be just a simple firewall rule, but I really can't figure out how to do it properly…
The local IP is the mail server and I have the DNS MX records for it on OPT2. If I don't do this, the emails try to go out through WAN [a lot faster] but all my emails are filtered by remote mail servers [which is logical, as it's a simple dynamic PPPoE link for end-users with no DNS records]
Use 1:1 NAT:
Define the WAN1 gateway in the firewall rule for source 192.168.1.201 on LAN tab.
For some reason I couldn't get 1:1 NAT to work properly. Kept messing up some other things…
However, the second suggestion worked flawlessly.
Thanks a lot guys, problem solved!
