UTM - Microsoft Teams

Hi everyone,

I'm with a problem on my company, that happened when on Microsoft Teams, i have more than 2 useres on same meeting.
I have a lot of freezes and sometimes i lost the connection. I already made a lot os tests ( networking, ISP, etc ), and i think the problem is on utm.
Anyone can give me some ideas to fix this problem ?

  • Hello Steve,

    i am also faced with the same problem - can you clarify what do you mean by Normally also a firewallrule for UDP Dest. Ports 3478:3481 is needed.

    This is what i made for the firewall on my end;

    i have made some exceptions in the IPS section for UPD flooding (see attached)


    do let me know if i've made the adjustments correctly.

    thank you.
