What I learned/surmised yesterday happened in a whirlwind, so the details aren't quite clear to me yet.

> Node fine, no issues

> apply newly learned firewall rules, go to sleep

> wake up, see force close

> panic

> firewall logs show blocked IP's to node while sleep

> nuke firewall rules

The particular network firewall rule was 'Drop invalid state', which I don't fully understand and blindly applied as part of an overall hardening guide.

So, to attempt answering your question given my limited knowledge:

An offline node doesn't seem to cause anything to get stuck, but an online node with broken LAN routing appears to be a real issue.

Perhaps my node appeared as viable in the graph, accepted an htlc, but threw it in the fuckin trash? 🤷‍♂️
