How to adress another routers webgui on opt1 wan

[evewes]

I have built failover with wan and a opt1 as a wireless bridge to my neigbours wireless router-.
192.168.10.1(pfsense gateway)->192.168.1.1(neigbour gateway)
Is it possible to adress their webgui with á routing policy or NAT, sometimes in need change values in neighbours router?

PFSENSE OPT1–--cable--->Wireless router (DDWRT in clientbridge mode)------wireless----->Neighbour router---->Internet

You'll either need proper return routing, or to use outbound NAT to translate traffic going to that host.
