I also ran into a really odd iptables problem... when I meshed in the second app server node using wireguard, my egress filter rule was blocking outbound traffic on both hosts. After some fiddling, out of frustration, I flushed the rules out of iptables on both hosts - so no rules. And... iptables was still blocking the outbound traffic. I ended up having to reboot each host - and once I did that, things worked ok. Has anyone seen iptables go into zombie mode before?
@jerry I'm glad you were able to figure it out, despite the brain fog. I swear it took months before I could properly use my brain to solve complex puzzles after recovering from COVID.
@jerry
I once had problems because newer iptables on #debian is basically a compatibility layer using #nftables in the background. Flushing all rules with iptables would remove the nftables rules but not the #netfilter rules. I had to use iptables-legacy to flush the #netfilter rules.
@jerry I haven’t had Covid yet, that I know of, but a lot of people have reported what sounds kinda scary “brain fog “ , hope it goes away and you start feeling better
@jerry Oh dude, vibe. When I had it last it was hard enough to make instant ramen, can't imagine doing network infra debugging. I feel for you man, get well soon.
