SIP/Asterisk behind pfSense with changing WAN IP - invalid States
-
Spend some time to find an issue with invalid states after changing WAN IP address.
Unfortunately this is an old bug, but only systems with changing WAN IP address are affected.https://redmine.pfsense.org/issues/1629
https://redmine.pfsense.org/issues/4674
https://redmine.pfsense.org/issues/7285We use now static WAN IP as workaround, which works fine.
This is only an note to prevent other users to debug this issue again. ;)
