Webex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.

Installing a Video Mesh Node in the DMZ requires you to open TCP and UDP port 4444 in your internal firewall for full clustering functionality.

Installing a Video Mesh Node in the DMZ requires the external firewall to allow UDP traffic from ANY port to the address of the Video Mesh Nodes via port 5004.

Using internal Video Mesh Node also works due to Mobile and Remote Access setup for Webex Teams clients. A DMZ node is added for extra security.

Additional headers due to NAT encapsulation can cause the packet size to exceed the MTU.

When the client is behind a NAT they may be unable to determine the appropriate offset due to time zones.

The IP address specified in the connection data field may be an unrouteable internal address.

The encryption keys advertised in the SDP are only valid for clients not behind a NAT.
