solution is to use PC and bind two-way IP/MAC on the routing, that is, bind the MAC address of the outbound route on the PC, bind the IP address and MAC address of the PC on the route. In this way, the route must support IP/MAC binding, such as the HIPER router. 3. Use IP/MAC address theft + IP/MAC binding Simply change your MAC address and IP address to the same IP address and MAC address as those running the P2P Terminator software, and check how it is managed. This is a two-pronged approach.
