IPv6 Firewall settings

I have been using the 7800 very successfully for some years now with a home mail server on my fixed IPv4 address with NAT to my server.

I now additionally have IPv6 access and a /64 block of addresses all of my own!
NAT no longer required of course on IPv6 but how do I allow incoming traffic for port 80 (for my web-mail) and all the other usual ports for the mail server? I assume all incoming traffic is blocked by default?

I have already set-up an AAAA record for the mail server's fixed IPv6 address (just 1 of the 2^64 addresses I have at my disposal).

Anyone can walk me through the firewall set-up? I want to still retain the IPv4 access as well.

Can you confirm the full firmware version and model (we have a range of 7800 models)

This is the model without built-in WiFi.

Thanks!

Try using the 'Firewall >> Packet Filter' to open port 80 to your IPv6 address (you can change the 'IP Version' to IPv6 and add a rule just like a IPv4 rule)

Is this 100% secure, by the way?

When you open a port to outside world its never going to be 100% secure,
