FW stops workung after update

[chymian 0]

Cloudron updated to 6.1.2 and the same time, firewall started to drop packages:
in this case UDP 161/SNMP (and others) and NM-Management reported device down, so I realized quickly.

just restarting the FW with systemctl did not solve the pbl. had to reboot.

@chymian-0 Did you whitelist the ports or did you use iptables/ufw directly? We only support https://docs.cloudron.io/networking/#whitelist-ports
