I am stucked with the following setup

OpenVPN set to access 3 subnets 192.168.16.0/24,192.168.32.0/24 and 192.168.125.0/24

So far i was using only the two first subnets with a dedicated interface for each of them

LAN 1 for 192.168.16.0
LAN2 for 192.168.32.0

I have added 192.168.125.0 with an IPAlias on top of LAN 1 and it works fine (the pfsense can ping inside this subnet)

When i connect on my VPN, it properly route the traffic as I have seen that if i trace 192.168.1125.50, it goes through the VPN.

I am stucked there, meaning that the trace stop with 10.0.8.1 and do not go further.

I assume I miss a rule in my firewall but where?

Thanks for your help.
