General
|
|
VTun is the easiest way to create Virtual Tunnels over TCP/IP networks.
It support various tunnel types and provides many useful features:
- Encryption
- Compression
- Traffic shaping
VTun is easily and highly configurable. It can be used for various
network tasks:
- VPN
- Mobile IP
- etc

Tunnel Types
|
|
-
IP tunnel (tun).
Supports point-to-point IP tunnel.
-
Ethernet tunnel (ether).
Supports all protocols that work over Ethernet: IP,IPX,Appletalk,Bridge,...
-
Serial tunnel (tty).
Supports all protocols that work over serial lines: PPP,SLIP,...
-
Pipe tunnel (pipe).
Supports all programs that works over Unix pipes.
|
|
Protocols
|
-
VTun protocol over TCP.
Allows to establish tunnels behind firewalls. Very reliable.
-
VTun protocol over UDP.
Fast and efficient protocol with small tunneling overhead.
|
|
|
|
Compression
|
-
Deflate (zlib).
Very efficient compression. Supported for TCP only.
-
LZO (lzo).
Super fast compression. Supported for UDP and TCP.
|
|
|
Encryption
|
-
Challenge based authentication.
No clear text passwords.
-
BlowFish 128 bits key.
Fast efficient encryption with 128 bits MD5 hash keys.
|
|
|
Traffic Shaping
|
-
Platform Independent Traffic Shaper.
Allows to limit inbound and outbound speed of the tunnels.
|
|
|
Platforms
|
-
Linux.
RedHat, Debian, Corel, etc.
-
FreeBSD and other BSD clones.
FreeBSD 3.x, 4.x, OpenBSD, Apple OS/X etc.
-
Solaris.
Solaris 2.6, 7, 8, 9
