I have a range of systems on a 10.1.4.X network. This range is connected to a router that routes that traffic to the 10.1.1.X network. The 10.1.1.X network is what communicates with the pfSense firewall which has a WAN/LAN port that is 172.16.100.26/10.1.1.17. There are 2 gateways, the WAN gateway is 172.16.100.1 and the LAN gateway is 10.1.1.18.
All machines in the 10.1.4.X network can ping this WAN/LAN port on both adresses.
There is a static route setup in pfSense for 10.1.0.0/17 to go to the LAN port in pfSense (10.1.1.18). The Automatic NAT Outbound mode was used and traffic is allowed to the internet through the WAN.
The router can ping 8.8.8.8 successfully as well as the WAN gateway (172.16.100.1). However, none of the 10.1.4.X machines can ping the WAN gateway or out to the internet. Even though they can ping the WAN/LAN pfSense...
