Preface:Your corporation’s financial system if the system makes the friend visit, but not the branch to undertake expensive line cost?Your home office ERP whether hope more nonlocal branch use at the same time, but you only ADSL?Your employees are frequent business trips, need often through CDMA use of the company’s business system, but lack good means?Whether you system long-term connecting multiple branch much computers, convenient for daily data maintenance and management, but the lack of a reliable solutions?Eisen software VPN system can help to you.A, eisen software VPN features:(1) as long as you can ADSL, simply setting once, installed VPN server software, multiple branch can easily visit your VPN network server where. The diagram below, VPN servers in subnet P, can be VPN client D access. As long as the server access bandwidth enough, can support both more than 30 remote VPN client connection.(2) the server and client fault-tolerant performance is strong, regularly monitor network circumstance, if network interruption can automatically redirecting, realize nobody keep value, meet long-term and stable operation requirements. (server if using ADSL dynamic IP, even replaced IP address, as long as reconnect the Internet, the client can immediately recognize new IP, realize reconnect.(3) strong security and stability, all the data by compressing, use recognized openSSL technology, to realize mutual TLS encryption transmission key and private key mode to ensure data validation safety. After three years, a lot of user access to this VPN system identification, safe and reliable, easy to use(4) give requirements, our engineers can according to your actual condition, given the professional solutions, make great efforts to meet your request.2. Support various Internet connectionEisen software VPN support various Internet access, such as dynamic IPADSL, ISDN, MODEM, private IP area CABLEMODEM broadband, and new mobile access WLAN,GPRS, etc. User need only open 777 and 5,000 port, eisen software can pass through most agents and VPN gateway connection.Features: eisenVPN servers send existIDC, high efficiency, communication quality is stable.Inadequate: hosting server requires spending brushstroke hosting fees.Features: virtual on installation, through within the companyADSL Internet connection, for all over access services. Cheap, easy maintenance and management.If the user using ADSL share Internet, then need through Internet router mapping ADSL 5000 port to you install VPN servers computer above come, they can. Currently most of the router can set mapping function, as below:?? Inadequate: by ADSL uplink bandwidths restrictions, slower.Three. Realize the comprehensive network software VPN supports multiple function eisen network protocol, such asTCP/IP, UDP, ICMP, etc. To all sorts of LAN applications such as financial system, oa system, ERP,The MIS etc expanded to remote different network, virtual line effect. At the same time, it can support the vast majority of audio, video communication systems, video monitoring system, such as VOIP etc. Eisen softwareVPN to provide mobile users support.Compared with other VPN products:?Eisen software VPNOther VPN solutions& # 9312; The system structure and principlesOnly need to be installed in a normal computer virtual on software, in other computer installed in the virtual LAN software can, need not buy special hardware,Form must pass a VPN gateway or take VPN function can be achieved; the router& # 9313; Realization cost analysisPure software way, is another solution for fractions of cost,Need each access nodes have VPN function of buying a router, or every node configuration a gateway, have hardware input costs.& # 9314; Executive conditionJoin VPN computer doesn’t need real IP, and only need in installing on computer have fixed IP can, implement simple;Need each node have fixed IP, conditions the demand is higher,& # 9315; Management &maintenanceOn any one computer at any time to join VPN system, only need the simple software configurations.Need to connect gateway or router whole subnet join VPN system, convenience and flexibility and security are deficient,Three powerful.NAT penetration function? 1) mobile VPN users with NAT subnet user one-way visitThe diagram above, subnet P one-way visit client D, or clientD one-way visit subnet P (in NAT Settings). Each change direction, want to visit restart NAT process.2) mobile VPN users with NAT subnet two-way access userIn the diagram above, because subnet P has 2NAT program in a separate run, so can also achieve subnet P and client D two-way access.3) two NAT subnet one-way visitIn the image above, so as to realize the subnet P1 to visit, or the one-way P2 subnetP2 of unidirectional access (P1 on NAT in Settings). Each change direction, want to visit restart NAT process.4) two NAT subnetwork interconnection of two-way accessIn the diagram above, because each subnet P1 and P2 2NAT program in a separate run, so can also achieve subnet P1 and P2 of two-way access
