I am currently doing a test for our OpenVPN setup through Pfsense, we have 2 Pfsense running on the network,
- For the default gateway of the LAN Network as Main Firewall.
- For the OpenVPN Clients as a secondary Firewall.
Based on my Test, I successfully Connect the OpenVPN client to the Secondary Pfsense however I can't ping the LAN devices except for the OpenVPN Pfsense LAN interface which is 192.168.0.4. I've also put the Ipv4 local networks that will be accessible from the remote endpoint in OpenVPN server setup which is the 192.168.0.0/24 LAN. Right now our LAN devices are pointing to 192.168.0.1 which is the Main pfsense. But when I tried to change the default gateway with one of the LAN devices I can receive a reply when I ping from the OpenVPN client. I also tried adding a static route to the main pfsense and the ISP modem for the OpenVPN Tunnel Network 192.168.3.0/24 and received no reply when pinging from the OpenVPN client.
I would like to ask if putting a static route is possible? or am I missing any configuration? like firewall rules or NAT? or another way?
This is the Topology of the setup:

Please Enlighten my Knowledge.
