Displaying DHCP Relay Statistics
To display information about DHCP Relay, type S on the DHCP Relay
menu. When DHCP Relay is enabled, the IAD displays this report:
215 Client requests forwarded to DHCP server
1 Client requests dropped
190 Server responses forwarded to DHCP clients
0 Server responses dropped
2 Unknown server responses
7 Server requests timed out
Press any key to return to the DNS Client menu when you're done
reviewing the information.
When using NAT on the IAD, it is often desired to configure a host behind
NAT as a Telnet Server. In this case, Telnet requests are passed to the
host, and not handled by the IAD. By changing the Telnet port, both the
host and IAD may be accessed via Telnet.
To set the port for the Telnet Server, follow these steps:
1. On the Router Configuration menu, type T to select Configure Telnet
Server Port.
2. The IAD displays the current IP address and a prompt:
Enter Telnet Server Port: (23)
Type the new Telnet Server port (the default is 23).
3. The IAD saves the changes and displays the Router Configuration
menu.
4. Continue with other configuration tasks, or press Escape to return to
the Main menu.
5. Reset the IAD (page 14) when you finish router configuration.
IP filtering allows for selective deletion of incoming and/or outgoing
packets. The IAD inspects each packet, and based on configured filters,
allows them to pass or deletes them. This feature may be used as a
firewall to only allow known good packets to pass though the IAD.
NOTE
Because each packet must be tested against one or more
filters, IP filtering may significantly affect IAD performance.
To configure IP Filtering, type F on the Router Configuration menu. The
IAD displays the IP Filtering Configuration menu:
