Internal and External on One Server ( ?? SplitDNS ?? )

[dbotham at edeltacom.com]

Uhhhh, No.


1.  Obtain a copy of the Bv9ARM.  Here:
http://www.nominum.com/resources/documentation/Bv9ARM.pdf

2.  RTFM, paying particular attention to the section(s) on Views.

3.  Use One name server to run 2 "Views" for each of the domains in
question.  One "view" for external users and one "view" for internal users.

4.  Grab cold beer from frig and relax...

Okay,

So what I am thinking of doing is this:

I add an Extra Server to my internal network running Bind 9. I then setup
this extra server so that every 30 minutes cron runs a script which FTP's
the zone files and named.conf from our public NameServers, the script them
replaces the public IP addresses in the zone files with our Private IP
addresses and writes them to disk and reloads Bind.

Does this sound reasonable? Any ideas, comments appreciated?

Thanks
