Host whitelisting for IPv4 / IPv6

[stefnats]

Hi,

i have a dyndns domain, let's say myhost.dyndns.org which solves to an IPv4-Address (A record). However, firewall seems to detect my current IP as an IPv6 (which is correct, too), but it can't whitelist this way.

Do you have any idea how to solve this problem?

TL;DR i have IPv4 and IPv6, dydns solves to ipv4, but firewall detects only ipv6

Having a similar problem with IPv4/IPv6 detection and blocking in my case. This way the blocking can be bypassed.
