Try PktFilter

http://sourceforge.net/projects/pktfilter/


PktFilter is a software that can configure the IP
filtering device driver found in Windows
2000/XP/Server 2003, with filtering rules following a
syntax similar to IP Filter. 

Windows 2000/XP/Server 2003 IP filtering device driver
offers the following features: 

-filtering by interface, on input or output 
-filtering on source and/or destination IP addresses 
-filtering on TCP/UDP ports, source and/or            
destination, with a pseudo-gestion of TCP established
connections 
-filtering on ICMP type and/or code 
-filtering of any layer 4 protocol, by specifying the
protocol number 

In Windows 2000/XP/Server 2003, IP filtering is
usually configured by the routing and remote access
service (RRAS), either via a dedicated MMC snap-in or
in command-line with netsh. With PktFilter, it becomes
possible to disable RRAS and only use PktFilter for IP
filtering.
