IPsec VPN refers to a VPN technology that USES IPsec Protocol to achieve remote access. IPsec is fully known as Internet Protocol Security, and is a Security standard framework defined by Internet Engineering Task Force (IETF). It provides secure communication channels for two private networks on the public network, and ensures the Security of connection through encrypted channels -- it provides private data packet service between two public gateways. IPSEC is a relatively complete system of VPN technology, which provides a series of protocol standards.

There are two reasons for importing the IPSEC protocol. One is the original TCP/IP system, which did not include a security-based design. Anyone who can jump into the line can analyze all the communication data. IPSEC introduced complete security mechanisms, including encryption, authentication, and data tamper-proof capabilities.

Another reason, because the rapid development of the Internet, access is more and more convenient, many customers hope to be able to use this kind of Internet bandwidth, to achieve the interconnection of the network.

Through packet encapsulation technology, IPSEC protocol can use Internet routable address to encapsulate the IP address of the internal network and realize the interworking of the remote network.

E-Lins 4g modem with ethernet port is 4g industrial grade router with VPN functions like IPsec, PPTP, L2TP, GRE tunnel. E-Lins routers can all support VPN, such as H685. Our VPN function can support many areas, like Australia, if interested contact us freely.
