Remote Replication

Hi,

I there anyway I can find some documentation on the bst practice of Remote Replication / Backup’s. I run 3 ISA firewalls two on mi side and one on the DR side and there is always a constant drop in connection. This means refreshing al 3 firewalls before connection is restored. I am using suresync to transver data. I didnt setup this crapy connection and was wondering if there is any sort of guid setting up a connection simmilar to this.

Regards
