Transit WG routing issue

meray

I am trying to set up a Transit VPN from A to C over B, so ABC. I am using WireGuard and the connections AB & BC are working, just not transitively AC. Everything else is explained in the diagram below, does anybody have any idea what could be going wrong?

@meray to recap:

on A you got routes to BNet and VNet using wgB as gatway
on B you got a route to VSub using wgB as gateway
on B you got a route to ANet using wgA as gateway
wgA, wgB and wgC have route/access to VNet
wgB and wgC have also route/access to VSub (a subset of VNet)
for wgA, peer B you set AllowedIPs to BNet, wgB and VNet (but not wgC?)

Questions:

are the Wireguard endpoints assigned as interfaces in pfSense?
are you doing NAT on Wireguard traffic?
is C -> B -> A working and only A -> B -> C not?
wgA has direct connection to VNet, why set the gateway to wgB?
is there a route to wgC on A?
what firewall rules have you set up for Wireguard?
