Nortel Business Secure Router 222 Configuration — Advanced
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging
management information between network devices. SNMP is a member of the
TCP/IP protocol suite. Your Business Secure Router supports SNMP agent
functionality, which means that a manager station can manage and monitor the
Business Secure Router through the network. The Business Secure Router
supports SNMP versions 1 and 2 (SNMPv1 and SNMPv2).
Network Address Translation (NAT)
NAT (Network Address Translation — NAT, RFC 1631) translate multiple IP
addresses used within one network to different IP addresses known within another
network.
Traffic Redirect
Traffic Redirect forwards WAN traffic to a backup gateway when the Business
Secure Router cannot connect to the Internet, thus acting as an auxiliary backup
when your regular WAN connection fails.
Port Forwarding
Use this feature to forward incoming service requests to a server on your local
network. You can enter a single port number or a range of port numbers to be
forwarded, and the local IP address of the desired server.
DHCP (Dynamic Host Configuration Protocol)
With DHCP (Dynamic Host Configuration Protocol), individual client computers
can obtain the TCP/IP configuration at start-up from a centralized DHCP server.
The Business Secure Router has built in DHCP server capability, enabled by
default, which means it can assign IP addresses, an IP default gateway, and DNS
servers to all systems that support the DHCP client. The Business Secure Router
can also act as a surrogate DHCP server, where it relays IP address assignment
from another DHCP server to the clients.
