A customer has Veritas 9.0 installed on BM 3.8 SP4 NW6.5 SP5. When Filters are disabled the backup will work correct. With filters the backup fails. I made a filter acception on port 10000 but this will not work. I tried a range of ports 10000 - 10100. High ports are open.

What is wrong? It has worked fine in the passed with the same filter exeption port 10000.
