According to the network safety connection issues due to the geographic location distribution of the coal enterprises in remote areas,the paper proposed to apply the IPSec Safety Protocol to the connection plan of the enterprise internal networks between two different mining areas through the Internet with the internal network gate strategy of the virtual private network to control the system.With the original data at the transmission terminal sealed and packed with a high strength and dynamic changed pass words in another IP channel and the front address of the channel as the IP address of the receiving terminal,the safety of the data could be ensured and the target to safely extend the coal enterprise network could be reached.An effective solution was provided to the hard to be connected for the safety data tunnel between the two networks caused by the network address translation devices existed in the network outlet between the enterprise mining areas.
