I'm on the periphery of a 3cx install that isn't going well. I'm really only responsible for the firewall piece and there are bigger issues than what I'm seeing with the firewall checker results, but wanted to make sure my component in this isn't a problem going forward. I have run the firewall checker against two firewalls with similar results, one a sonicwall tz 300 and the other a watchguard t30. Both were configured per their respective instructions from the 3cx site. Sometimes, the tests will actually pass without issues (on both firewalls), but more often than not, 1 or more udp ports (9000-9500 range) will get remapped. The message will be 'Mapping does not match 9126. Mapping is 9127'. On the sonicwall side I have ensured the source port remap setting is disabled on the nat policies. Anyone seen anything like this? Thanks.
