Abstract
There are provided a packet transfer device, a semiconductor device, and a packet transfer system, which can provide a DMZ constructed in a simple configuration. A LAN is connected to a first port. A public server is connected to a second port. A WAN is connected to a third port. A filtering section performs filtering processing according to attributes of each packet inputted via any one of the first to third ports. A routing section carries out routing processing on the packet which was not discarded by the filtering section.
