Title: No video/voice on Skype
Post by: iask on June 25, 2021, 07:55:52 am

Hi Guys,
could you explain how to use Skype behind OPNsense firewall.
I can log in successfully, chat working but can't make video and voice calls.
I tried to fix by activating NAT reflection but it didn't help.
When I remove firewall and connect to ISP directly no such problem occurs.

Does OPNsense have a public IP address on the WAN side or are you using double NAT?

I suspect my WAN isn't public, IP discoverable on site IP location is different to WAN ip I get from my ISP

I am behind auto outbound NAT, that's all

also I am a bit confused by this option "Dynamic gateway policy" This interface does not require an intermediate system to act as a gateway. But looks like it doesn't help much.

You may be behind CGNAT which will make things very difficult. What is your public IP address on the WAN periphery?
