Adjustable TCPip connection tracking - RMerl/asuswrt-merlin.ng GitHub Wiki

Under Tools -> Other Settings there are various parameters that lets you tweak the timeout values related to connection tracking for TCP and UDP connections. You should be careful with those settings - they rarely need to be changed, except when dealing with special scenarios that might need it. Most commonly, people will tweak the UDP timeout values to make them more VoIP-friendly, by using smaller timeouts. Timeout values are in seconds.
