Problem description: When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files. Problem Analysis: These problems are often caused by the identification of data packet fragments by devices during data transmission.

MIP is a "one-to-one" two-way address translation (conversion) process. Typically, there are several public-network IP addresses, and there are several servers providing network services (the server uses a private IP address), in order to enable

SSG-5 is the Juniper Firewall entry level products, some emergency situations need to log into the intranet of a PC or server, need to temporarily open the firewall 3389 ports and do the corresponding VIP mapping.
