- Checking IPs is almost useless, check MAC address 有一点用 (无内容) - JJZ (0 bytes) 2008-12-05, 11:58:51 (281454)
  - mac address doesn't propagate through IP network. (无内容) - steven (0 bytes) 2008-12-05, 12:04:28 (281458)
    - e.g - JJZ (772 bytes) 2008-12-05, 12:21:11 (281465)
      - that mac address will be stripped by the router. (无内容) - steven (0 bytes) 2008-12-05, 12:23:51 (281468)
        
        you are right, - JJZ (104 bytes) 2008-12-05, 13:10:42 (281505)

        you are right, L2 Tunneling is part of the TCP/IP family now. (无内容) - steven (0 bytes) 2008-12-05, 16:09:17 (281601)
        
        well, L2TP (Layer 2 Tunnel Protocol) supports encrypted tunnels over IP network. - JJZ (38 bytes) 2008-12-05, 15:40:55 (281591)
