Nortel VPN Router Configuration — Basic Features 

 

Control tunnels are special tunnels that allow you to securely manage a Nortel 
VPN Router over the Internet. The primary reasons for creating control tunnels 
are secure management and network data integrity. Control tunnels provide secure 
access to a customer’s remote Nortel VPN Router so that you can manage it over a 
network. Control tunnels also guarantee that no data from the network behind that 
customer’s Nortel VPN Router could be accessed by anyone on the network who 
manages the Nortel VPN Router.

You can allow access to FTP, DHCP, RADIUS, and DNS servers from the Nortel 
VPN Router through the control tunnel. Control tunnels allow you to easily 
configure secure tunnels to any Nortel VPN Router that you want to manage. This 
allows you to set up an encrypted tunnel to a customer’s Nortel VPN Router. 
Through that tunnel you can perform all the necessary management tasks, such as 
HTTP, FTP, SNMP, and Telnet.

where a central VPN server can control several VPN devices and configure 
services, such as RADIUS, FTP backup, SNMP Traps through Web client 
management, or Telnet.

Note: To establish a control tunnel over a NAT connection, use 
IPSec-capable NAT. Control tunnels cannot establish a connection while 
the Nortel VPN Router Stateful Firewall is enabled when you use the 
Autodetect IPSec-capable NAT feature.
