Reverse telnet with portforwarding

can i forward the perticular revertelnet data from any of the async device to the perticular host using NAT/PAT?

like one end having multiple async devices connected to router and other end is router connected with server so can i send the multiple revese telnet port data to the server with the help of NAT/PAT by using different line number buind with the server ip address?

Re: Reverse telnet with portforwarding

Cisco IOS software has for quite some time included a feature called Reverse Telnet, whereby you can telnet to a certain port range and connect to terminal or auxiliary lines. Reverse telnetting has often been used to connect a Cisco IOS router that has many terminal lines to the consoles of other Cisco IOS routers or to other devices. Telnetting makes it easy to reach the router console from anywhere simply by telnetting to the terminal server on a specific line. This telnetting approach can be used to configure a router even if all network connnectivity to that router is disconnected. Reverse telnetting also allows modems that are attached to Cisco IOS routers to be used for dial-out (usually with a rotary device).

Reverse SSH.
