When many users configure the sniff and command of the VPN virtual network card of the lingke router, they need to monitor the traffic of the virtual network card, but do not know how to set it, next I will introduce the VPN configuration of the lingke router. I. Through software, sniff can be performed on the virtual network card of the VPN Server. Three types of software are tested on the server and the client respectively: Sniffer pro, tcpdump, And the built-in Network Monitor (1) sniffer pro cannot find a virtual VPN Nic, so it cannot monitor the virtual VPN Nic. (2) tcpdump can monitor the virtual VPN Nic, whether on the server side or on the client side, once the virtual VPN Nic is monitored, although the VPN is still in the connection status, however, the VPN can no longer be used because it cannot work. (3) The MS network monitor can work normally without affecting the use of VPN. It can also monitor the data flowing through the VPN network card through sniff virtual network card. (1) netsh ras set user administrator deny # forbid administrator to dial in the VPN; (2) netsh ras ip set addrassign method = pool # assign IP addresses using address pools; (3) netsh ras set user administrator permit # Allow administrator to dial in the VPN; (4) netsh ras ip show config # view the IP Address Allocation Method of the VPN; (5) netsh ras show user # view which users can dial into the VPN; (6) 6 netsh ras ip add range from = 192.168.3.1 to = 192.168.3.254 # The address pool range is from 192.16 8.3.1 to 192.168.3.254.
