@telnetdoogie thanks for the detailed response.
I hadn’t realised that the script uses the WAN rules which explains why certain ports were open despite me seemingly not opening them. I have a port forward rule which allows ports 80 and 443 which for IPv4 is fine as it’s NAT and I control where the traffic lands but for IPv6 the ports are exposed to ALL devices it seems.
I’ll have a play with the rules and see if I can tighten them by adding IPv6 specific rules around my existing rules.
The most concerning for me was traffic being allowed from the internet to my UDM-SE.
Thanks again for this brilliant write up and your additional support.
