Accessing all pfSense Subnets from OpenVPN Server (thinking its a Firewall Rule issue)

[DaHai8]

I have a RPI4 VPN Client connected to a RPI4 VPN Server over the Internet.
The server is on 172.27.3.100
The client is on 192.168.1.100 on a pfSense box
The client pfSense network also has: 192.168.2.0/24 and 192.168.3.0/24 on their own physical Ethernet Ports.

To the Server config, I added:

route 192.168.0.0 255.255.0.0
client-config-dir /etc/openvpn/server/ccd/

in the ccd folder, I added a file of the client name of the .opvn file it is using( client). Into that file I added:
iroute 192.168.0.0 255.255.0.0

After rebooting the Server, I can access and ping any device on 192.168.1.0/24 (where the client lives) from the Server side.
But I cannot access or ping any device on 192.168.2.0/24 or 192.168.3.0/24.
However if I log directly in the client (not through VPN), I can ping and access all the devices on the other two networks.

I've gone over the OpenVPN docs for "Including multiple machines on the client side when using a routed VPN (dev tun)":
https://openvpn.net/community-resources ... er-subnet/

It's just one client to one server, so I don't believe I need routing to all clients.

So this appears to not be a VPN issue, but maybe a Firewall Rules setting in pfSense?

Like its blocking access to the other two networks (192.168.2.0/24 and 192.168.3.0/24) from 172.27.3.0/24 because it's not a native local network?

Any ideas?
Need more info?

This appears to resolve this issue:

iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE

Thanks everyone for all the help

@DaHai8 pfsense doesn't use iptables - so no clue to what your talking about.. That sure didn't fix it.
