Hi Brian,

You can effectively block ports by using TCP/IP filtering (e.g. WinXP) and probably other Windows platforms.

There are four Registry Values for TCP/IP filtering in the key:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
where the specific settings for each interface are configured in the key:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\Interfac e_GUID. <---Note: no space

The Registry values to configure TCP/IP filtering are:
EnableSecurityFilters: DWORD Type; 1 enables TCP/IP filtering; 0 disables it.
UdpAllowedPorts: MULTI_SZ Type; 0 allows all UDP ports; an empty (null value) blocks all UDP ports, otherwise, the specific allowed UDP ports are listed.
TCPAllowedPorts: MULTI_SZ Type; 0 allows all TCP ports; an empty (null value) blocks all TCP ports, otherwise, the specific allowed TCP ports are listed.
RawIpAllowedProtocols: MULTI_SZ Type; 0 allows all IP protocols; an empty (null value) blocks all IP protocols, otherwise, the specific allowed IP protocols are listed.

Looks like a lot of work to get it right without a tool. You might try searching the MS website for: Tcp/Ip filtering +tool
or the MS Technet.
