Hello,
we use a UTM 9 Version 9.506-2 and have to open the Ports for WhatsApp.
All tipps in the forum won't work for me. So i hope, that someone can help me.
I opened Port 5222, 5223, 5228-30.
Excluded the four Regex for Whatsapp...
But the communication is very unstable.
Anyone who has a solution?
Kind regards
Hendrik
