Im a bit dump stuck.
Im running PBX Firmware: 12.7.3-1703-1.sng7 thats the current beta 14/14
What ever I do, everything wokrs, all the clients and ext. are working fine and gegistering. As soon as I activate Fail2Ban, some, and not always the same of my extensions drop out. But their IP address does not show up in the Fail2Ban gui inside the FreePBX gui.
I first had it with my cell phone and the zoiper free client, even whitelisting the IP of the cell didnt help. Stopping fail2ban solfed it instantly. reacitvating it, the dead cell was back…
Anyone got any good idea?
