NAT public IP through multi way

lukeluke1979

Evening,
I have a Pfsense box with two way.

First way, WAN is connected through radio PTP with private ip to a Mikrotik router that is connected to ISP

Second path, tunnel GRE with the same router Mikrotik (created by FTTH PPOE)

I have a public subnet /30 routed on the two paths with different weight (primary FTTH and Radio like backup)

I would like NAT the LAN with the public subnet /30

How can I do?

I am thinking to configure the public IP /30 like Virtual IP on the LAN interface. So it is independent from the output interfaces. And then create Nat rules.

What do you think?

Thanks a lot

Ps. Sorry for my bad English, I'm Italian

There is no need to assign the public IP to sn interface. Just add NAT rules on both WANs with custom translation address.

@viragomann thanks a lot. From lan to wan works right.
I must test how it works for some internal exposed services.
