The virtual private network old many VPN protocols, PacketiX VPN provides a full layer 2 (Ethernet) take-off for VPN data transfer. In other words, with old layer 3 VPN solutions, encapsulated IP packets flowed through the tunnel, but with PacketiX VPN, these are Ethernet packets in place of.
Since VPN came to wider use around 1998, variouse VPN protocols have started to become popular, among them:
* PPTP (GRE)
* L2TP / IPSec
* vtun
* OpenVPN
* Port transmission by SSH
Although, older version of VPN solutions have limitations as Mentioned under, which makes them Tough to use under various Situation.
Difficulties to pass network gateway devices:
Internet we can use from company LANs and small localy at home networks is normaly managed by a gateway device, be it a small hardware router or a Linux server, which serves as firewall, proxy server and router with IP masquerading (NAT). While such a gateway provides necessary functions for the management and security of the network, it can be a barrier for older VPN solutions.
Since old VPN protocols do not ship received Protocol packets, they are ofttimes obstructed by firewalls and routers which don't know how to hold specific protocols equivalent GRE or IPSec. If the IP is not decent masqueraded by the router, VPN computer and computer are unable to ground a unification. Thusly, experienced VPNs compel either bespoken devices, or primary firewall and router settings, which affirm time to set up, may not be feasible in every design and effort lessen mesh guarantee. If the router cannot palm the specific rule hired by the VPN or the VPN rule cannot grip masqueraded IPs, a global IP is required for both consumer and server.
In all types satuation, PacketiX VPN is able to instaled a connection out of the box and without any reconfigurations, special hardware or global IPs. This saves money and reduces administration effort.
Network protocols other than TCP/IP can't be transferred:
Acording to rule and regulation VPN protocols can only Simulation a network up to OSI layer 3, the network layer (IP), unlike PacketiX VPN, which takes the technology one step further by emulating Layer 2, the data link layer (Ethernet).
Although, previously a dedicated line was necessary to transfer legacy network protocols such as IPX/SPX and NetBEUI, which are still required by some devices, over a VPN. PacketiX VPN makes it possible to transfer them over the Internet with a software VPN solution.
