I don't know what your setup is but I myself explicitly FORWARD things to telnet: e.g: # Allow access to machines from the private LAN: iptables -A FORWARD -i INTERFACE_CONCERNED -o OUTPUT_INTERFACE -p tcp \ -s $LAN_MACHINES --sport $UN_PRIVILEGED_PORTS \ -d $DESTINATION_ADDRESS --dport 23 \ -m state --state NEW -j ACCEPT you get the hint. Any way why use telnet? I recommend secure shell (tcp port 22). Santos. Security is a blessing.
