No remote LAN Access and Internet after connecting to the VPN

[rameshkumar]

We have two firewalls in our network as below:

1. PFSense - 192.168.1.3
2. Fortinet - 192.168.1.2

Some of the workstations are configured with PFSense IP address as their default gateway and few other hosts are configured with the fortinet firewall IP address as default gateway.

We have recently configured the OpenVPN server within the PFSence and able to connect from the remote office. But unable to access any LAN machines that are configured with the Fortinet firewall IP address as their default gateway. We are able to ping the PFSense IP address from the remote office after connecting to the VPN. Remoe clients are unable to access the Internet as well after establishing the VPN connection. Could any one help us to solve this issue?

Thanks in advance.
