This is interesting, I tried the portfw sample from the howto like
so:
--------------------------------------
port=2000
while [ $port -lt 2020 ]
do
/usr/local/sbin/ipmasqadm portfw -a -P tcp -L 10.1.2.3 $port -R
192.168.0.10 $port
port=$((port+1)
done
--------------------------------------
It didn't work. So I modified it like so:
--------------------------------------
PORT=2000
while [ $PORT -lt 2019 ]
do
/usr/sbin/ipmasqadm portfw -a -P tcp -L <my ext ip> $PORT -R
<internal icq user ip> $PORT
PORT=`expr $PORT + 1`
done
--------------------------------------
This worked fine. Now I see another way from Jesper Jenson like
this:
--------------------------------------
port=2000
while [ "$port" -le 2100 ]
do
/usr/sbin/ipmasqadm portfw -a -P tcp -L HereIsMyLinuxBoxIP "$port" -R
192.168.0.2 "$port"
let port="$port"+1
done
--------------------------------------
I'm running RedHat 6.0 and using the bash shell. Will different
systems and shells require different syntax?
