ALLOW ZOOM AND TEAMS IN MX

[Fernando_R]

HELLO, I WANT TO KNOW IF ANYONE HAD THE NEED TO DENY ALL OUTGOING TRAFFIC TO THE INTERNET AND ALLOW ONLY THE MICROSOFT TEAMS AND ZOOM APPLICATION. I TRIED TO DO IT WITH A GROUP POLICY, BUT I STILL CANNOT ACCESS THE APPS.

It doesn't look like you have a rule for DHCP/DNS.

This may or may not be required depending on your setup and design.

Have you verified whether users are able to obtain an IP and can resolve the domain names?

Have you verified that the firewall rules are applying correctly? (Eg. Performing a telnet for the TCP ports)

If the above are successful, you may be missing some specific rules for the applications.

Users receive IP and navigation is enabled, they can access the Internet. I understand that it may be an issue of ports to enable, and that is why I ask if both with teams and with zoom, someone could solve this.

Done this plenty of times for Teams.  Are you seeing any hits on your Deny Any rule at the bottom?

What are you seeing in your wireshark traces from the LAN?
