	There are a number of companies who deal with protocol layer
brdiges that can do packet filtering.  Proteon, Bridge and Cisco come
to mind.  Some are even programmable enough that you can define new 
protocols (i.e. Apollo/HP 8019...).  You should look at a number of 
vendors before you buy.  There are many options/limitations with many
models.  Look hard at what you need to do v.s. cost.
