IP Router

IP router pattern filters are applied to IP Ethernet frames that are

being routed.  When the  P850 is operating as an IP router, all IP

routed frames will be checked against the defined IP router pattern

filters.  IP routed frames are unaffected by the bridge pattern filters

and the IPX router pattern filters.
