[Networker] Problem recovering SQL data across a firewall

We've run into an issue recovering  alarge (around 27GB) MS SQL database
across a firewall between a Windows 2003 box in production behind a
Check-Point firewall and a Windows 2000 server that we use just for test
purposes. Our Legato server is Power Edition on a Sun Solaris 9 box with
a Sony PetaSite and S-AIT tape drives connected to our v480 server via
fibre channel. All of our network equipment comes from Nortel.

I have a call open with Legato on this issue. As far as I know, ournetworkadministrators have a call open with Nortel on this issue. So far,nothing morethan head scratching has taken place since we first discovered thisissue a

few weeks ago.

When a colleague of mine tries to do a test recover of a 27GB SQL DBacrossour firewall, the recover proceeds for a couple of hours. During thistime, I believethe SQL module is building the tables and other infrastructure tohouse therecovered data on the target server. After that phase of the recoveris done,it just dies with a connection error in the target client's daemonlog and in the

NetWorker server's daemon.log. We see no other errors.

When the same equipment is used to recover a large set of non-SQL files

across the same firewall, the recover succeeds. When my colleagueattemptsto recover small SQL databases in the same conditions, those recoversalsosucceed. The kicker is that when we can recover the same large SQLdatabaseif we do the recover to a target server that resides in the samesubnet where our

NetWorker sever resides.

If anyone has any thoughts on where we should look to resolve thisissue, orwhere our network administrators should look, I would be grateful tohear fromyou. Fortunately, we are doing this only for DR testing purposes, butwe do need

to get this to work in case a real DR takes place.
