Nortel VPN Router Troubleshooting
Dynamic password
Two types of administrative users exist on the VPN Router:
• one super-user (Administrator)
• as many administrative users as needed
There is dynamic password support for administrative users only. The
Administrator still requires a static password.
RADIUS manages the dynamic password. The external RADIUS service acts as
an intermediary between the VPN Router and the dynamic password
authentication system.
To configure a dynamic password:
1 Select Profiles > Users and click Add User.
2 Under Administration Privileges, select Dynamic Authentication.
When enabled, this forces administrative users to authenticate through
RADIUS, which then forwards authentication credentials to a dynamic
password authentication system, such as SecurID. The privileges associated
with this administrative user are configured as before.
Tools
The VPN Router supports standard IP tools such as ping , Traceroute , and ARP
show and delete . You access these tools through the Admin > Tools window.
The ping command generates an ICMP echo-request message, which any host
can send to test node reachability across a network. The ICMP echo-reply
message indicates that the node is successfully reached.
