"Thumbs up," but an even better article for your situation might be this one:
Updating downloads in an internal LiveUpdate Administrator 2.x Server using the downloads from an external LiveUpdate Server
Article: TECH106254
Article URL http://www.symantec.com/docs/TECH106254
(Here is an informal article on why it is better to always got to external networks - A Helpful LiveUpdate Administrator 2.x Analogy - but if that closed network has ZERO internet connectivity possible, this "sneakernet" method may be your best solution.)
A few questions.....
- Which version of LUA are you using?
- Which Symantec products and versions are being updated? (SEP 11 or SEP 12.1? Also, any additional Symantec producst getting updated-?)
- Does the LUA on the closed/internal network distribute to many Distribution Centers, or are you using just its default clu-prod?
With answers to those I may be able to provie you with some additional advice.
Thanks and best regards,
