1 main office with pfsense and openvpn server, windows 2019 server
network class 192.168.1.x
4 locations with pfsense at each location and openvpn client with server 2019
network classes
192.168.2.x (tunnel openvpn 10.0.2.x)
192.168.3.x (tunnel openvpn 10.0.3.x)
192.168.4.x (tunnel openvpn 10.0.4.x)
192.168.5.x (tunnel openvpn 10.0.5.x)

I have activated a fifth office but in this case I have installed vmware with:
pfsense
server 2019
two networks running on two network cards
one card goes to the internet router
the other card on the internal LAN
pfsense configured and running
the network works

in this case, however, openvpn clients connect to the remote network, from the remote network I pin this pfsense but strangely I cannot ping the server
network class 192.168.111.x (openvpn client 10.0.111.x)

the only difference is that in this fifth network the server is a separate domain
could that be the problem?
