Port forwarding

Hi,

we have an issue with webex port (UDP 9000). Team claims that it gets redirected to port 443 though port forwarding is not configured. When they bypass proxy it works. how to troubleshoot such issues?

Thanks,

Sridhar

Re: Port forwarding

Hi Sridhar,

Hope you are doing well.

This looks to be an general/expected behavior.

The Cisco WebEx client will first attempt to connect to the server using a UDP
port. If the port connection cannot be established  the Cisco WebEx
client will then establish a server connection using the TCP ports.

 

Also for your general  info you can get UD traffic via MWG using SOCKS.
