I have a problem I can not seem to solve.
I have a Branch office router that is making an OVPN to Main.
I am making a WG interface to the main.
Everything on the Main network works over WG but Branch I can not reach.
HOWEVER there is also a L2TP connection to Main, and that one can reach Branch no problem:
Topography:
VPNs (client) -------------------- Main ------------------------OVPN ---------------------- Branch
WG 10.0.10.2 ----------------- 192.168.10.0/24 --------10.0.13.2---------- 192.168.13.0/24
L2TP 10.0.13.2
The Branch subnet is routed to the OVPN GW on Main (Network DST 192.168.13.0/24 to GW 10.0.13.2 at distance 1)
Branch has allow on input chain for VPN address IPs.
As stated L2TP has no problems going trough, however WG can not reach it.
Is WG in some way special that it needs sth extra? On client side? On server side? NAT perhaps?
