VTun (Virtual TUNnel) is software that lets users create Virtual Tunnels over TCP/IP networks.
It support various tunnel types and provides many useful features including encryption, compression, and traffic shaping.
This is free and open source software.
Key Features
- 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. It allows you to establish tunnels behind firewalls.
- 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 you to limit inbound and outbound speed of the tunnels.
