Two months ago, I replaced the Ubiquiti USG3P router with a more capable UXG Gateway Lite, which is better in almost every way.
However, I had a problem with idle TCP sessions closing after 5 minutes, which is a real bummer with SSH sessions.
I finally figured out how to fix it.
In short, a default setting is missing a 0.
To fix, login to the router's SSH console, and type sysctl -w net.netfilter.nf_conntrack_tcp_timeout_unacknowledged=300
