Below are two (edited) runing pix configs - a main and a brach office.
I've been asked to create a new secondary DNS server for the brach on it's
local lan. The primary DNS
server is sitting on a Windows 2003 server on the main office's :LAN. I
feel this is mostly politics and not not driven by bandwidth issues - but
in any event, does anyone see likely probelms here ? Is there anything about
these PIX configs that sould get in the way of DNS records being moved from
one DNS server to another ?
