Scenario Operation Procedure
In above diagram, Network‐A is in the headquarters, and the subnet of its Intranet is
10.0.76.0/24. The security gateway for Network‐A has the IP address of 10.0.76.2 for
LAN interface and 203.95.80.22 for WAN interface. It serves as a PPTP server.
However, Network‐B is in the mobile office and the subnet of its Intranet is
10.0.75.0/24. The security gateway for Network‐B has the IP address of 10.0.75.2 for
LAN interface and 118.18.81.33 for WAN interface. It serves as a PPTP client.
PPTP server provides two user accounts, User‐1 and User‐2, for PPTP clients dialing in.
Establish a PPTP VPN tunnel by starting from the PPTP client site. So both Intranets of
10.0.75.0/24 and 10.0.76.0/24 can securely communicate each other.
Finally, the client hosts in the Intranet of Network‐B at mobile office can access the
server or database resources in the Intranet of Network‐A at HQ in a secured link.
