ok, let me explain this.

The transparent proxy is for use in situations where you are on (say)
210.my.ext.IP and you telnet "172.20.11.5 7100" with a rdr rule like
this:

rdr e1000g0 0.0.0.0/0 port 7100 -> 210.172.133.140 port 1 tcp

It will cause the connection to 172.20.11.5 to be terminated locally
on the ipfilter server at port 1.  This is the only scenario that
requires the use of tproxy.

*IF* you are on 210.my.ext.IP and you want to connect to the
Internal Server automatically and the command you use is
"telnet 210.172.133.140 7100" , you would do:

rdr e1000g0 0/0 port 7100 -> 172.20.11.5 port 7100 tcp

*IF* you are on 210.my.ext.IP and you want to connect to a proxy
on the ipfilter server and have the proxy connect to the Internal
Server then you do not use rdr rules or ipnat, you just use a
TCP relay program.
