I am not sure if this is my iptables or not, but I am not sure where

computer. From inside my network, it works fine, but once I get
outside, I cannot use it. I have set my IPTABLES to forward anything
going to port 3389 to the computer that is using Remote Desktop.
The problems seems to be that port 3389 is filtered. I can find
nothing in my iptables where I have this port filtered. Are there
some generic ports, that IPTABLES filters on it own or something? If
the IPTABLES are not filtering it, what else could be?
You allow forwarding to this host but you also need to DNAT these
packets from the internet IP to the IP of your computer.
$ipt -t nat -A PREROUTING -i <if_inet> -d <ip_inet> \
-p tcp --dport 3389 -j DNAT --to <ip_controlled_host>
<apology>Rob, sorry for sending this to you first - I always forget to
fix that...</apology>
If it still doesn't work, it's quite possible that your ISP is filtering
that port upstream of you.
