Thanks, that's pretty much what I thought but that brings up another
question. Does the DNS have to have a public IP address, i.e., one that is
valid on the Internet or can it use a 10-net address provided the Internic
record of all hosted webs, etc have been changed to point to a valid IP
address outside of the NAT? My understanding from all of the docs I've been
reading on NAT tell me that the router will pass the DNS request through the
NAT and resolve correctly, right??
Does anyone know if "The NAT Handbook" by Bill Dutcher adequately addresses
topics such as this?
Thanks again,
Jeff
