Is it possible to use the PORT_FORWARDS variable to specify that all
external traffic arriving on <some port> be forwarded to an internal
host on port 23 ?

For example, I've tried setting PORT_FORWARDS like this:

PORT_FORWARDS="$EXT_IP(26)-192.168.1.102(23)"

so that incoming external traffic on port 26 would be forwarded to
server 192.168.1.102 (behind the firewall) on port 23 (the telnet port)
but when I try doing a telnet on port 26 to $EXT_IP (from outside the
firewall) I get no response.  Telnet connections to host 192.168.1.102
port 23 inside the network are no problem (as they were before I made
these changes), so I know that the telnet daemon on host 192.168.1.102
is active and working.

Am I barking up the wrong tree?
Thanks,
Steve
