To accomplish the ‘spo<strong>of</strong>ing’, you must configure the <strong>Sidewinder</strong> <strong>G2</strong>s<br />

generic TCP proxy to listen on port 23, and enable it to spo<strong>of</strong> the<br />

original workstations IP address (refer to the “use_client_address”<br />

feature in the /etc/sidewinder/conf/tcpgsp.conf file). The administrator<br />

must also enable the rule list allowing internal to external traffic from<br />

the Telnet client to the Telnet Server for the generic TCP proxy. Also,<br />

to pass the RIP information through the <strong>Sidewinder</strong> <strong>G2</strong>s, both systems<br />

must configure and enable the routed server.<br />

Again for discussion purposes, the administrator must use the Admin<br />

Console to configure routed on the Internet burb for the following<br />

options:<br />

Advertise routing information: yes<br />

Advertise as default gateway: no<br />

Receive routing information from other routers: yes<br />

Routes from burbs: none<br />

Also, routed on the trusted burb must be configured as follows:<br />

Advertise routing information: yes<br />

Advertise as default gateway: no<br />

Receive routing information from other routers: no<br />

Routes from burbs: Internet (2)<br />
