UDP timeout?

Hi Y'all,

Just wondering, when pfSense (RC3) is managing the firewall state table, if there is a UDP timeout metric in play? And, if so, is there a way to change it? We're getting UDP timeouts periodically on long running UDP based internet transfers, and I'm trying to find the cause of it. Just wanted to rule out pfSense as a possible source of it…?

Many thanks!

It wouldn't remove an active state with traffic on it, but there is a timeout. You can change to value by changing the "firewall optimization" setting in the advanced options. Conservative will make it hold onto UDP states for a lot longer.

To view the current timeouts, go to Diagnostics > Command (or the shell) and run: pfctl -st

Great! I've just done that, we'll see how it works. Thanks very much!
