OpenVPN routing problem from Office to Branch network

[Sateetje]

We have different OpenVPN instances running on pfSense.

P2P and Remote Access. Both types have same problem.

It worked until a while ago... Don't know which change is causing the issue. Maybe changing to PPPoE for 1 WAN connection?

Issue:
From clients (ra) or branch network clients (p2p) to office network everything is fine.
From office network to clients or branch network clients there is a routing problem.

This is the info of an RA setup:
Tunnel network: 192.168.105.0/24
pfSense tunnel ip: 192.168.105.1
Client ip: 192.168.105.2

Ping from pfSense to 192.168.105.2 is fine (from source address LAN)
Ping from office pc to 192.168.105.2 is timeout

Tracert -d 192.168.105.2 will show a public IP of the PPPoE connection as first hop.

Routes on pfSense:

192.168.105.0/24	link#17	U	20	1500	ovpns4	
192.168.105.1		link#8	UHS	21	16384	lo0

@Sateetje Ping from office pc to 192.168.105.1 is fine as well

@Sateetje I think I have found it. I had an allow all rule at the bottom of the rules on the LAN interface. In the rule I set the default gateway to a gateway group, look like this was the issue.
