I would use the internal 192.168.1.252 address since it is local to the LAN. Using the external address would create traffic to your ISP and back again I think, or at a minimum would create traffic and IP mapping on your NAT router that the LAN address would not.
In both cases, however, as you probably already know but I share for the benefit of others, you are using your internal DNS server for address lookups. That means that your DNS needs to be recursive, is a potential source of being spoofed/compromised, and is another point of failure in sending with LRP (and whatever other services us it). I used to use my own DNS for external lookups and then decided to just bang on the ISP's servers as they were really set up for it. I use my DNS now only for machines needing internal only addresses and as external authoritative for domains that I host.
