Routeing Problem With Gateway In LAN [Solved]
Hello, I am looking for some help to solve a routing problem.
I have a pfSense machine setup as a typical router.
The LAN interface is assigned the subnet 192.168.1.0/24
It has an additional (not the default) gateway set up (192.168.1.3) and a static route to send packets with the destination 22.214.171.124 to that gateway.
If I send a UDP packet to 126.96.36.199 from any computer in my LAN it makes it to this gateway computer successfully.
However I have a VPN setup on one computer that is experiencing issues.
When this computer, also in the LAN, tries to send a packet to the pfSense machine (the packet has the destination of 188.8.131.52 and the source address 184.108.40.206) the packet does not make it to the gateway.
When running a packet capture I can see the packet enters the LAN interface, however gets dropped for some reason and does not make it back out.
So my question is what setting can I change so pfSense wont drop the packets that have a source IP not found in the subnet. I had this problem before on an Ubuntu server and found I had to turn off Reverse Path Filtering.
More context can be found in my question at http://unix.stackexchange.com/questions/316642/routing-packets-from-one-interface-to-another if needed.
I finally realized that it was default LAN Firewall rule that was only allowing packets from a LAN subnet IP address.
