Yeah, my computer has an application firewall[0] between it and anything that tries to connect to it (LAN or not), so if my router ever opened up my ports, I would know.
Same applies for my other two computers (my MacBook runs Little Snitch on 10.14, so it's a kernel extension that Apple can't bypass). Not the rest of my devices though. Though it's not like anyone could get through fail2ban on my server, or compromise my Android device, or hack any IoT devices since I own none, etc.
