Multi-wan gateway originating traffic

[proxykid]

EDIT: resolved.

Hi,

So far multi-wan has been working OK in my setup (OPNsense 19.7.8-amd64) if a link goes down default gateway switching does is thing.

We currently have 3 ISPs and 1 LAN port in the gateway.

Currently this is the setup:
ISP1 (100/100 DHCP, default gw)
ISP2 (10/10 Static, deprecated, to be removed)
ISP3 (200/200 Static, new one)

Anyway, I have a VPN connection working through the default gateway but it has a dynamic IP and I'm attempting the VPN to be able to receive connections through a the new service (non-default/non-active) gateway but it doesn't work.

When I try to connect to the VPN via ISP3 I ran packet captures and incoming traffic as expected comes from a the non-default gateway ISP3, but the outgoing packets are trying to go via the default gateway (ISP1) instead of the same WAN port it came from (ISP3).

Am I missing something?

Thanks

Nevermind, classic case of finding the solution after asking for help. Was unaware of the localhost workaround.
