Custom resolve an URL?

[av_bell]

A server is accessed externally using a xxxx.dyndns.org address and is connected to the internet via a DSL router with a dynamic IP. Clients that need to have access to the server both internally and externally need to for example configure two mail accounts, one with the server set to xxxxx.dyndns.org and the other one set to 192.168.0.x.

I need advice or some starting points on how to set up DNS (if this is the service that I need) on Mac OS X Server 10.3.9 so that it does the same job as the internet provider’s DNS server but resolves the xxxxx.dyndns.org to 192.168.0.x for local clients.

Also, why is it that on networks with a DrayTek router the computer name in the terminal prompt is set to the last segment of the IP address?

Thanks in advance.

Ugh, well, I can think of two ugly ways to do it.

Option 1: Set your server to host dyndns.org. home1.dyndns.org will always resolve to 192.168.0.10 for instance. Note that this will, um, break any resolution for anything other than the fakey DNS records you create in your bogus dyndns.org zone. Yuck.

Option 2: If you don’t want to break resolution for everything ending in dyndns.org (including http://www.dyndns.org! ) , use another of their free domains, or fork over the money to dyndns.org for your own domain name. dynadrian isn’t taken 🙂 Have your server serve up your bogus domain to the local network, but everyone outside your local network will get resolution from dyndns.org.

In either case, point your internal clients to your server for DNS service, and allow your DNS server to recursively look up DNS for everything else it is not already serving.

Ugly.
