Manual:Virtualization

•• offer virtual routers with VPN solutions that give a network administrator customer his own router on a highspeed

backbone to make any kind of tunneled intranet or simply VPN access system

At the wireless ISP client site

•• set up two isolated routers and set the wireless control only for the router controlled by the WISP while the

Ethernet side router is fully under the clients control

At multiclient sites (such as office buildings)

•• in locations serving multiple clients by Ethernet from one backbone connection (wired or wireless), give each

customer control over his own isolated virtual router

For network planning and testing

•• build a virtual network on one box with the same topography as a planned network and test the configurations so

that the fine tuning of the configurations can be done in the lab and not in the field, simulate and monitor the

network with advanced scripting and The Dude network monitor utility

In custom applications

•• develop your own programs (and even Linux distributions) that can be installed on MikroTik supported platforms

with minimum difficulty as software patches and virtual drivers are provided for guest systems

•• use low cost RouterBOARD embedded systems easily with your own Linux and the advantage that it will work

across all RouterBOARDS with the same CPU

Use Metarouter to Implement Tor Anonymity

Software

This article describes the steps to set up Tor Anonymity software behind a Mikrotik Hotspot using a Metarouter

instance. The Metarouter image presented here is for RB4xx MIPSBE boards that support OpenWRT Metarouter

images.

The end result is a NATed network that routes only encrypted tor traffic for end users. The only ports that are open

to end users include 80 tcp, 53 udp, 8118 tcp and 9050 tcp. 8118 tcp is the Privoxy proxy which acts as a standard

http proxy to the Tor Socks proxy. Provoxy also has enhanced privacy features such as "removing ads and other

obnoxious junk" [1]. Port 9050 tcp is the Socks proxy available for routing traffic through the tor network. All other

ports are blocked for security and anonymity reasons. This configuration may be used to set up a wifi network which

automatically routes traffic through tor.

Tor Background

What is Tor?

Put simply, Tor is anonymity software that protects a source computer from eavesdropping by a third party. Tor

routes internet packets through a series of encrypted proxies. Each proxy in the chain knows a part of the request, but

not the entire request. The destination server also does not know what the source is. Tor may also be referred to as

Onion routing. Tor is an open source project run by volunteers from around the world.

From the Tor web site [2]

"Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security

on the Internet. It also enables software developers to create new communication tools with built-in

privacy features. Tor provides the foundation for a range of applications that allow organizations and

individuals to share information over public networks without compromising their privacy."
