This feature applies to the HTTP proxy, HTTPS proxy, and SOCKS proxy. Through this feature, data destined for a specific IP address and port can be forwarded to a corresponding IP address and port. Therefore, when internal users access internal resources through the proxy server, requests can be forwarded directly to the corresponding LAN server.

The destination address can be an IP address or a domain name, but the destination address for data forwarding must be an IP address.

For example, configure a forward entry to forward the access to www.Sangfor.com.cn (through port 443) to the LAN server at 10.1.1.3 (through port 443). The corresponding configuration is shown on the following page:

Health Check Options: You can specify the health check method, L4 health check, or L7 health check, and action if the forward refuses to work, Stop forwarding data, or Continue forwarding data. HTTP or HTTPS probe packets are required to perform the L7 health check.

To specify the health check interval, click Advanced, as shown in the following figure.

Interval (mins): The interval is a global setting. It should be an integer between 5 and 60 minutes.
