Image 54: NetCom Manager Firewall Panel 
Many networks use a Firewall to protect the stations in the network 
from other networks, including the Internet. In some situations the 
contact to a NetCom must pass through such a Firewall. To do this you 
must “Enable Firewall”, and enter the “Address” of the Firewall. 
The Manager configures a NetCom via SNMP, which uses UDP. The 
Firewall must have a special “Port” to receive those data, and to transfer 
it to the internal network. Enter this port here. 
The same scheme applies to the logging option. By default a NetCom 
listens on port 1200 for logging connections. The Firewall must also 
have a special “Log Port” to receive this connection, and to transfer it to 
the NetCom. 
The NetCom does not need any configuration to operate in a Firewall 
protected environment. This configuration here is for installation of the 
drivers. There is a Firewall tutorial section later in this manual.
