port forwarding not work

mkutz
hello,
i will control a remote computer with remote desktop connection at xxx.dyndns.org:2001. It works fine from a computer without firewall. now i will controll the pc from my pc behind asl 5.1.
1. i define a new service called "remote" that contains the port 2001 
2. i define a host (my PC)
3. i use SNAT/DNAT (see picture)
where is the problem???

    I see two possible things wrong.  

    1.  Your DNAT rules are looking for packets with a destination address of your workstation. I believe this should be the external address.  You should then have MASQ change the destination address to your workstation (This part looks right).

    2.  Do you have a packet filter rule which allows traffic from ASL to your workstation on port 2001?
