It's been years trying to figure out how to port forward the UDP ports of Echolink. I succeeded the two test and failed on the next one, so overall it is still failed on firewall test. UDP 5198 Test #1 ... Succeeded UDP 5199 Test #1 ... Succeeded UDP 5198 Test #2 ... Receive Failed (10054) UDP 5199 Test #2 ... Receive Failed (10060) I did this directly from my pfSense router, no other router in my network, even a wifi router. I made a firewall NAT and rules on pfSense firewall. Without the new rules everything is FAILED. With the Result of 2 success test it still a failure to Echolink Test. Anyone fix this issue, especially those who use pfSense as a main firewall router.
