    I have 2 LAN PC's behind an ADSL Router.

    I want to be able to allow PC1 to access the file shares on PC2 but I do NOT want PC2 to access the file shares on PC1

    This sounds easy but I cannot seem to get my head round bi-directional rules. If I only allow PC1 to PC2 using PC>>Internet the reply packets are dropped and therefore access from PC1 to PC2 is not available. If I allow PC1 to PC2 using PC>>Internet>>PC then not only can PC1 access PC2 but PC2 can also access PC1.

    When using the bi-directional rule the headings on Source and Destination are confusing - does it matter when using a bi-directional rule which IP addresses go in where as they both seem to mean the same on bi-directional rules.

    TIA

    Richard.

    Thank You for your help - I also saw another one of your responses with regards to SPI and this pointed me in the right direction of rule placement to stop externally initiated connections.

    Thank You once again - I am sure I will get my head round it eventually.

    Regards
    Richard.
