Note: When you set filters, make sure you allow the flow of packets going to the RPC
port (port 135 TCP or UDP), DCOM ports, and the Unified Manager port (port 443 TCP)
for correct Unified Manager operation. For more information about allowing Unified
Manager access, refer to
“Accessing Unified Manager through the Firewall” on page 829 .
To allow access for
SSH, you must set the filters to allow the flow of packets to the SSH
port (port 22).
To allow access for Telnet, you must set the filters to allow the flow of packets to the
Telnet port (port 23). If you block the Telnet port, you can still access Telnet using a direct
connection. To make a direct connection, you must be on site and you must connect the
LAN port on the Business Communications Manager to the NIC port on your computer
using an Ethernet crossover cable.
