• Howdy, have been running pfsense for several months without issue. Recently, though, one of our firewalls has been rejecting all attempts to ping it on the WAN side. Likewise, a 1:1 NAT rule that I have just implemented has failed. Firewall has been restarted and rule order switched around to no effect. Currently using 1.2.2. The ruleset is listed below. I opened a log rule to track ICMP packets and the log indicates that the packets are being passed through, but no response occurs from the WAN side.

  • Fixed, it was a routing issue where unused interfaces for testing were confusing the firewall as to where it should send the ICMP packets. Interfaces disabled, problem solved. My bad.
