By blocking all inbound TCP connections to the telnet port 23 to disallow all inbound telnet connections, if i wish to block all other inbound TCP connections, but i want to allow outbound telnet connection, what inbound TCP connections must i allow so as not to interfere with the outbound telnet connection? which are the ports that are needed to be open for outbound telnet connection? and what and if i were to use the bits in the TCP header, which bits can i use to perform the same action as described above?
