Hi,

 

i have a small/big problem.

 

We are using Fortigate 200E with Proxy Policy (web Proxy), and we have a problem with Cisco Webex, the Stream is not working and a Networktest from Cisco says that our UDP 5004 Port is blocked.

 

The problem is, that in Services under Explicit Proxy only TCP avaible is and not UDP and Socks-UDP not working.

 

We tested the stream with our WLAN, whitch working whithout Proxy and there is the stream working.

 

How it's possible to actived or open the UDP Port under explicit proxy

    Hello guys,

    I am the same issue. We have lots of area using web proxy but we cant enter proxy policy session udp. Do you have any solution for this. Udp 443 is blocked.

    You will indeed not be able to squeeze UDP traffic through a TCP-based explicit web proxy, just like you can't run ping (ICMP) through it.

     

    Typically apps that support web proxies have an option to enable this. If this app insists on using UDP, and cannot be switched to TCP, then presumably it simply doesn't support web proxies.

     

    And if the app doesn't support it, you can give it an exception and let it pass through directly (without proxy).
