Hi,
The issue is that the dns cache for the host to IP address is not flushed
when you transition from one network to another. So your internal IP would
be used externally or vice versa.

My suggestion is to consider using the public IP for both internal and
external DNS entries.

...which is why I use the public address only. Yes, it does go out and back
again when I'm in the office but it works everywhere.
