The TCP-UDP-proxy is a low precedence policy that allows all outbound TCP and UDP traffic from networks protected by your XTM device. If you remove the Outgoing policy, and do not want to add a separate policy for each type of traffic you want to allow out through your firewall, you can add the TCP-UDP-proxy. This policy only allows outbound TCP and UDP traffic, but it also monitors that traffic for HTTP, HTTPS, SIP, and FTP packets sent on non-standard ports. For the HTTP, HTTPS, SIP, and FTP protocols, the TCP-UDP proxy relays the traffic to the correct proxy for each protocol.
To add the TCP-UDP-proxy to your XTM device configuration, see Add a Proxy Policy to Your Configuration.

You can use the settings on this tab to set logging, notification, automatic blocking, and timeout preferences.
If Application Control is enabled on your device, you can set the action this proxy uses for Application Control.
For more information, see Enable Application Control in a Policy.
On the Traffic Management tab, you can select the Traffic Management action for the policy. You can also create a new Traffic Management action. For more information about Traffic Management actions, see Define a Traffic Management Action in v11.8.x and Lower and Add a Traffic Management Action to a Policy.
