Simple and known Multi-WAN problems

[OlegVekhov]

Hello all!

My task is simple - I  have multi-wan setup, and want to access web configurator from any of WANs.

But now I can access it only on main WAN, not backup WAN, since, as I understand, traffic goes backward through default gateway.

Read many about reply-to rules, played with settings, read https://docs.opnsense.org/manual/firewall_settings.html and many many other google hints

The simple question to guru/developers: can I acheive it?
