5. Configuring the FrameSaver SLV Router

IP Filtering
When NAT is enabled and the IP filters are active, filtering is done on the Ethernet
port: upstream first, then downstream.
Upstream: From the client to the server
Downstream: From the server to the client
Land Bug Prevention
The router drops all packets received on a network PVC interface or the Ethernet
interface when the Source IP address is the same as the Destination IP address.
Smurf Attack Prevention
The router ignores requests to send an ICMP echo reply to the broadcast address
and ICMP echo requests with a destination of the broadcast address.
Provisioning the Router Interface
The FrameSaver SLV Router defaults to bridge mode. Routing without bridging,
and simultaneous routing and bridging, are also options.
Use the bridge command from the router’s CLI to configure the bridge and routing
attributes. Also, enter an Ethernet IP address and a DHCP IP address.
Refer to Appendix C,
Router CLI Commands, Codes, and Designations
, for
command line syntax and information about CLI commands. For a list of default
settings, see
