Setting up End-User Access Creating a Network Filter 5 select those filters that "allow" certain types of connections. For example, you might only want to allow FTP connections. NOTE: If you set the default policy to Drop and you want to enable FTP connections, make sure you set the FTP connection type on the host to "active". (If you set the connection type to "passive" you can connect to the NSS but are not able to list, transfer the data, and so on.) STEP 3 Click Change Policy. Creating a Network Filter The Active Network Access Filters table on the Network Filters page displays currently defined filters. These filters control if access to the NSS from specified hosts is granted or denied on a per-protocol basis. Each device in your network is assigned a fixed 48-bit MAC address and changeable 32-bit IP address. When you define a filter, it grants or denies access via the specified protocol from the specified IP/MAC address or range of IP addresses. NOTE: When you define a new filter, any existing connections that would normally be denied by this rule remain in tact. These connections are denied during the next attempt to connect to the NSS.
