2 WAN IPs (same subnet+gateway) and 2 LAN subnets. Can I route to both WANs?
-
I have been trying to get this to work for ages, and looking through this forum I just can not seem to find anyone with my kind of setup and needs.
(i am referencing LAN as LAN1 and WAN as WAN1 below)
What I have is a ISP that delivers me 2 IPs, which I have assigned 2 NICs to - WAN1 and WAN2(OPT1).
My LAN has 2 subnets - 192.168.0.x (LAN1) and 192.168.1.x (LAN2(OPT2) or through IP Alias). The subnets reside on the same physical network, so using either a NIC or a Virtual IP (alias) is available for me.I want to make sure all traffic from LAN1 goes to WAN1 and all traffic from LAN2(or the alias of LAN1) goes to WAN2.
So far I have been able to get the 2 subnets work through WAN1 (with an alias on LAN1). I had to turn on AON and add a rule for the alias subnet, and a Firewall rule for the same subnet on LAN1.
Is it possible to do this kind of mapping when both gateways of WAN1 and WAN2 are identical? Or is this a no-go?
To narrow it down further. What I really want is to make WAN2 map 1 to 1 to my main computer, while the rest of my LAN uses WAN1.
Anyone able to help with some inputs?

Having two NICs in the same subnet with the same gateway does not work.
If that is a single ISP link, you don't want multi-wan anyhow. Just add the second IP as a Virtual IP (CARP or Proxy ARP) and then you can use it for outbound NAT for LAN2 as you want.

Problem with Virtual IP is that it is statically configured. It can not get its IP through DHCP. (?) And all 4 IPs I get from my ISP are all DHCP delivered. Unless there is a trick to get the second as well.
And thanks for answering.

Ah, well then that is a little different. You should have mentioned that up front.
I believe there are some other examples of configuring what you're after with DHCP on the forum here. I don't recall the specifics, but it wasn't an ideal situation.
