Hi,
i came to notice that when i enter a domain as ipsec peer address and this domain has only a AAAA record asigned to it, the routerOS does not establish a tunnel to the IPv6 endpoint.
When attaching an additional A record everything works fine.
Except that only IPv4 is used, where i would have expected IPv6 to be preferred.
With a plain IPv6 address it is working, i can also confirm that the DNS Server does correctly resolve AAAA queries to this domain.
Setting a static entry in the build in routerOS DNS server also does not help.
Is that a kown limitation?
