VyOS supports setting timeouts for connections according to the
connection type. You can set timeout values for generic connections, for ICMP
connections, UDP connections, or for TCP connections in a number of different states.

You can also define custom timeout values to apply to a specific subset of
connections, based on a packet and flow selector. To do this, you create a rule
defining the packet and flow selector.
