and end IP address edit box, enter the IP address, and click OK, Click OK; Tip: using a static IP address pool to assign an IP address to the client can reduce the IP Address Resolution time and increase the connection speed. You can specify the starting IP address and ending IP address (for example, 192.168.0.10 to 192.168.0.50). If the DHCP service has been configured for this host, you can also select Dynamic

Free and available IPv4 addresses will soon be "exhausted". Over the years, this has prompted most general operating systems to begin to add IPv6 support. However, many applications (such as VPN clients and server software) are not ready for IPv6. This will lead to the situation where the dual-protocol stack host deployment does not support IPv6 VPN software, thu

follows: IPSec host-as the client, you must provide the user name and password when connecting to the center. Edge device-as the server (center), the client must undergo password verification. When the VPN firewall is defined as IPSecWhen a VPN connection is established, the device will provide the server with the username and password information. When the

protect the integrity of IP data packets, which means that IPSec will prohibit any modification to the data packets. However, during the NAT process, you must modify the IP address header data of the IP data packet, transfer the layer-Report header data, or even transfer the data content (such as the FTP application. Therefore, once an IP packet processed by IPSec passes through the NAT device, the packet content is changed by the NAT device. After the modified packet arrives at the destination
