The Express L768/L1.5 can block packets in and out of a WAN port by use of 
the filters. They are set up in two steps: 1) define the types of packets that 
would be of interest in the Configuration/Security/Filter Defines menu, and 
2) set up the filter type and combination of defines that will cause a packet 
block.
