ie its resolvable ;) What is the point of registering it in resolver if your not wanting to resolve it?? ;) So yeah the desire/need to resolve is clearly debatable… Why should we discuss doing something that has no actual value??
Eitherway other than an override I do not know a way of registering that IP, which again could be lots of different IPs for each vpn client based upon their /30 What name would it be? If going to resolve it, has to have a NAME.. so just going to be pfsensename? or pfsense.openvpn.yourdomain.tld ? What name would you use to resolve it with? If just PTR, what name would it return?
Guess you could ask for a feature request or do some coding to come up with a name for these IPs being used.. So that it could be registered in resolver without override.
