Whether it's a good idea or not depends on what it's being used for.
Authentication by IP is a bad idea, restricting who can connect in the
first place and proceed to authentication stage is a further line of
defence, and in any case no worse than allowing the whole Internet -
except for a DoS condition in case of DNS poisoning. That's a tradeoff
decision though, and either direction is valid. Or what am I missing?
The DNS answer could also be sanity-checked (though not with pfsense) if
the possible IP range is known.

Using a VPN effectively integrates the client into the server's network
- do I really want that? And is the whole Internet allowed to attempt to
be a VPN client? That would be no better than the starting position.

Thanks,

Volker
