PacketiX VPN 2.0

Features

• High-speed data throughput
• Easily pass gateways, proxy servers and firewalls
• Server Clustering to meet heavy load and stability demands
• VoIP and QoS Support
• Virtual Layer 3 switching, virtual NAT and virtual DHCP server (see Architecture)
• Administration by script and command line
• Monitoring and logging of VPN traffic and packet contents

High-speed data throughput

PacketiX VPN is optimized to exhibit high performance for any line, from low speed lines such as a dial-up connection or mobile phone to high speed lines of 100Mbps or 1.0Gbps. A low-cost Pentium 4 2.8Ghz processor VPN Server is enough to handle a several hundred Mbps connection. PacketiX VPN increases packet delay by less than 1 msec.

In a test demonstration, the PacketiX VPN 64-bit Edition has reached a maximum throughput of 3.13 GB/s, on server hardware worth roughly 4,300 USD at the time.^*1

For increased network throughput and connection stability, PacketiX VPN can bundle several TCP/IP connections into one VPN connection. This function also helps to create a stable connection if the physical network is unreliable and causes heavy packet loss.

Easily pass gateways, proxy servers and firewalls

Since PacketiX™ VPN uses a protocol that encapsulates the data in TCP/IP packages. This makes it possible to establish a VPN connection over network gateway devices like firewalls, NATs, proxy servers and broadband routers without reconfiguration, where VPN solutions required special settings or failed.

In addition, any TCP/IP port number can be designated and used for VPN communications with PacketiX VPN. The default port numbers are 8888, 443 (HTTPS) and 992 (Telnet over SSL). Thus, even if port numbers are limited by the network environment, the software makes it possible to select ports freely.

With the flexible port selection it is no longer necessary to change firewall for PacketiX™ VPN, and no additional open ports means no additional security risks. It also allows to use the VPN Client on public Internet access points with restrictive security settings, such as WLAN hotspots in cafes, hotels or airports.

Server Clustering

Clustering is a method to enable the distribution of a large processing load between several servers. PacketiX™ VPN Server 2.0 offers clustering and load balancing features, which allow the handling of a large amount of connections, what a single computer would not be capable of doing. Even if one server goes out of service, the other servers automatically take over his jobs. This makes PacketiX VPN an excellent choice for environments where high reliability is key.

VoIP and QoS Support

PacketiX™ VPN 2.0 incorporates advanced priority control and quality of service technology, whereby packets for IP telephony are transmitted at minimum delay and low jitter even on a crowded network. The software automatically conducts priority control and secures bandwidth according to the priority information in the packet headers. Packets demanding low delay and jitter, such as for VoIP, can be given priority for VPN transmissions over other packets. This distinctly enhances sound quality when using IP telephony via VPN, even when networks are congested with traffic such as file downloads.
