What happens when someone else is assigned your old network numbers and puts a web server on the address you're using for your "old DNS server"? Then your customers can't see it. Bad. A better solution might be to use an "intranet" subnet, such as 192.0.0 (or 192.x.y, where x and y are arbitrarily chosen). This would require notifying all your customers who use hard-coded DNS servers, but you could do this well in advance. You could then keep track of who hasn't switched yet, using a combination of RADIUS and a packet logger. The other problem is that QuickDNS Pro can't be configured to forward in the way you mean. BIND can, though, and Linux or BSD is available for whatever old Mac you plan to use for this. If you don't want to learn Linux (which can be daunting at first), you could make QuickDNS Pro (or Lite - check Info-Mac) work with network address translation (aka IP masquerading or transparent proxy service). There are two such products available for the Mac. IPNetRouter (from Sustainable Softworks, <http://www.sustworks.com/>) provides outbound (client) translation, which you might be able to make work. VicomSoft's Internet Gateway (http://www.vicomsoft.com/) also performs inbound (server) translation, and that would definitely work. Be aware that there have been reports on the list recently that QuickDNS Pro doesn't like being on a machine with multiple addresses, specifically with VicomSoft's products, and may become unstable as a result. However, you could put VIG or IPNR on another machine and use it as the DNS resolver's router. Hope this helps ________________________________ Chris Buxton Internet and Database Consultant
