VPN + DNS

[dgiorgio]

how do I ping the host for vpn?

ex:
root@pc1# ping PC3

admin@pfsense2# ping PC1

[dgiorgio]

is this possible?
I have to do some configuration in OpenVPN, DNS or DHCP?
have to change the structure of the network?
need a DNS server on the 192.168.4.0/24 network?

the pfsense already connects the pfsense2!

I did a routing on the router 192.168.4.1

Any destination 192.168.0.0/23, redirects to the IP 192.168.4.117

entire network 192.168.4.0/24 can ping the pfsense.
