Configuring system settings

The Nortel VPN Router can be booted in one of the two system modes: safe mode
or normal mode. Each mode has its own software image, configuration files, and
LDAP database.
A system booted in Safe mode is only allowed to accept secured management
tunnel establishment. When the secured management tunnel is established, Telnet,
HTTP, and FTP traffic is allowed to come into the Nortel VPN Router; no other
VPN traffic is allowed through the secured management tunnel or the Nortel VPN
Router. In Normal mode, the system operates with the normal software and
