Virtual private networks / Re: traffic between vlan clients stops when client starts his local vpn client

« on: April 11, 2023, 12:49:32 am »

The locals on the same vlan can reach the vpn client even when the openvpn is running.
I just would like to know how to config opnsense to allow me to reach then vpn client from another vlan.

Virtual private networks / traffic between vlan clients stops when client starts his local vpn client

« on: April 10, 2023, 07:49:44 am »

wan <--> opnsense (vpn_gw) <--------> VLAN20 --- desktop
                                                     \ ----> VLAN60 --- server1 (openvpn client)

My first opnsense setup and struggling with routing configuration.
The server on vlan60 is reachable from vlan20.
The moment server1 start it's own openvpn client the routes change and i cannot reach it from vlan20, desktops in vlan60 are though able to reach it.
I need help, my attempts with single gw and routes config were futile.  :'(
