Define TCP Proxy Protocol parameters

The TCP Proxy Protocol Agent is a legacy proxy agent that allows closing connections after a set amount of idle time.

Note: The TCP Proxy Protocol Agent is only supported for NGFW Engine version 6.1 or earlier. For newer versions, use the SSM TCP Proxy Protocol Agent.

Certain TCP-based applications do not properly handle closing of connections but instead leave them open for a long time, unnecessarily consuming resources. For such situations, the TCP proxy agent can be used to actively close the connections after a certain idle time. The TCP Proxy Agent can also close a connection if connection closing initiated by one of the communicating parties does not complete in a timely manner.

Apply this Protocol Agent strictly to those TCP connections that require this feature. Proxy operations use more resources than normal TCP connection handling and therefore increase the firewall’s load.
