IPv6 'single host' rule selects a /32
-
I'm setting up a rule to allow outside traffic to pass through to a single internal IPv6 address on a handful of ports. When setting up the destination match for the rule, 'Single host or alias' selects and locks '/32' as the CIDR prefix length. In case the problem isn't clear already, allow me to elaborate—to specify a single host on IPv6 needs a CIDR prefix of /128. A /32 will select everything routed to me and more.

Try setting it as a Network with a /128

That appears to be purely cosmetic. Continue creating the rule. Even if you submit at that point with the /32 showing the correct host rule is created.
For me when I move on to the destination address that /32 is hidden again.

Switching to 'Network' and back to 'Single host or alias' did indeed clear the prefix length. I'm going to operate under the assumption that it's cosmetic, as you suggest Derelict. Thank you both.

Thanks for pointing it out:
