Hi Is it possible , to do telnet to a destination on specific port with specifying the source address fron cli on checkpoint gaia R77.30 appliance ?
Not using the telnet command, but you can do something similar with the nc command (available from expert mode).
Yes, this is the venerable "netcat"
The GNU Netcat -- Official homepage
If you just want to test connectivity with telnet you can also use pinj instead, the packet injector tool created by Check Point.
