No audio over VPN

[JosephInFL]

We had some changes to our client VPN. Now when a user connects via VPN to the LAN that the 3CX is on, they can't hear audio in- or outbound. The same laptop will work fine if connected directly to the LAN so it's pretty definitely the VPN or the firewall rules. Can someone direct me in the first things to look for? I did set the firewall rule for VPN clients to access all services on the LAN.

Does port 5090 to the 3CX server pass traffic?

Update: I opened up the VPN firewall rule to not restrict traffic between VPN nodes and the LAN. Audio is working now.
