relationship between the SNMP manager and an agent. The community string acts like a password to
permit or deny access to an agent on the Router. The defining characteristic associated with the
community string is the Access Right. The agent's access right can be set as either read/write or read-
only. Under Traps enter the Destination IP address and Trap Community Name so that the agent
sends traps to the management server. The Trap Version can also be set to either SNMP V1 (to
specify that SNMP version 1 will be used) or SNMPv2c, which supports both centralized and
distributed network management strategies. SNMP V2c includes improvements in the Structure of
Management Information (SMI) and adds some security features.

The following window will aid the router's administrator in configuring filters for IP addresses. There
are two types of filters that the administrator can configure. Outbound Filters are for administrators
who wish to deny clients on their LAN from accessing certain virtual ports or IP addresses on the
Internet. Inbound Filters are for administrators who wish to deny IP addresses or virtual ports from
outside the router (on the Internet) from accessing the Internal LAN of the router. Click the
corresponding radio button to configure Outbound or Inbound Filters. Both screens are identical in
configuration.
