    Well first of all let me ask a couple of questions..

    1- Does you office PC have real IP or a private IP
    2- Is your office PC behind a firewall or not
    3- Do you have a static IP or a dynamic public IP at your office >

    If you're on a network in the office, i would recommend you use Hamachi, the free version is sufficient.

    Install this on your office PC and on your home PC. You then have a VPN.

    You can't have dyndns connect to each individual PCs directly unless you want to use a specific application on it which uses a specific port. This is because dyndns only resolves your public IP and not your private IP.

    Eg. you have a ftp server on port 21 on PC1 and you have an remote control application on port 5900 on PC2.

    So you set your router to port foward port 21 to PC1 and port 5900 to PC2
    Then when you want to connect using dyndns to the ftp server on PC1 you would do and when you connect to PC2 you would go

    You connect your home PC to the office PC by either --

    1.  a private VPN between the home and office -- best done with a VPN router.
    2.  By using VMC software, like realVNC, TightVNC, VNC, or similar programs -- the office is server, the home PC is the "listener" in this sceanrio.

    It does not work by DNYDNS -- that is for making a real IP number out of a virtual one.  However, you might need this DYNDNS program to make a real IP out of the home or office IP if you are using DSL on either end, which uses only VIRTUAL IP numbers.  It makes a SINGLE computer into a reachable IP number, but it does NOT make the computer to computer connection for you.  You need VPN or VNC to do that.
