I am seeing some strange behavior in pfSense 2.0.3 in which all of my WAN interfaces are up according to the Interfaces screen, yet all but the default gateway are shown as "Offline" in gateway groups.
My default gateway works just fine.
My first thought was that the gateways do not respond to ICMP, but I am able to ping them from an unrelated connection (ie from outside) just fine.
Even stranger, using the "Ping" tool in WebConfigurator I can ping 8.8.8.8 from all of the WAN interfaces, yet they cannot ping their own next hop.
Strangest of all, when I use an alternative monitor IP of 8.8.8.8 for any of the interfaces, it stops being pingable!
I am wondering the following:
- Does the Ping tool in WebConfigurator still have the firewall and outbound NAT rules for localhost applied to it?
- Has anybody seen anything like this before?

I have almost the same issue on pfsense ver 2.3.2-RELEASE-p1 After hours of googling I found this. https://forum.pfsense.org/index.php?topic=105644.0
Sometime gateways do not want to response to
ping. If your gateway's working but dashboard still shows that it's offline you can try changing the advanced settings on the gateway for Data Payload. (Define data payload to send on ICMP packets to gateway monitor IP.)
