Approach

We will use an approach based on ARP(Address Resolution Protocol). The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol.[1]

Suppose we are host A, and there is a host B in this P2P network. What we have to do is pretend to be B’s MAC address and reply B’s ARP request. Then all the data that host B accesses the network will pass through host A first, and the returned data will also pass through A. At this point, we can simple to manage host B’s flow. The advantage of this approach is small capital expenditure, and can implement this technology on one host, you can manage the entire P2P hosts in the same router.
