Managing local and remote domains

My method for solving this problem is to have a local DNS with two views:
- internal view (recursing), responding to internal clients with local
- external view (not recursing), that is used as a hidden master for my

No forwarding, the local server does all its own resolving, the hidden
master controls all the outside servers.

The downside is that you must maintain both views, typically with
different data, unless you only have public addresses. Some management
tool might be a good solution for this.

The good side is that your laptop users will not have to know whether
they are inside or outside your network - e.g. your mailserver is in all cases, inside it has a 192.168.x.x address and
outside it has a.b.c.d so mail programs never see any difference.
