$OUTERIP = External IP
$INTTARGET = NT4 Server

.
    /sbin/modprobe ip_masq_portfw

/usr/sbin/ipmasqadm portfw -a -P tcp -L $OUTERIP 8000 -R $INTTARGET 8000
/sbin/ipchains --append input -p tcp -s 0/0 -d $OUTERIP 8000 -j ACCEPT

And from /usr/share/doc/ipmasqadm-0.4.2/redir-vs-portfw.txt

                REDIR2                       PORTFW
Place           user-space                   kernel

Method          connection "bouncing         reversed masq "spot"
                  at firewall"

Pros            . easy installation          . fast, low-resource
                . no kernel-side support       consumption
                  needed                     . load-balacing in LAST
                . load-balancing               patch-sets
                                             **internal servers SEE
conns
                                               from ACTUAL client **

Cons            . 1 process/connection       . kernel-patch needed for
2.0
                **internal servers SEE       . masquerader timeout
                  ALL connects from            handling may affect
                  firewall (NO WAY :)          total available connects
                  thus turning access        . usable, but still under
                  logs useless **              devel/test (THE Linux way
;)
                . process-handling:          . LOCAL (@firewall)
redirection
                  susceptible to scheduling    not available
                  issues
Resource        1 process/connection         1 masq entry/connection
usage                                          limited to max. masq
                                               entries
