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.
