===== Emulating a WAN connection =====

[[http://wanem.sourceforge.net| WANEm]] is used to emulate a WAN connection, enabling the control over bandwidth, latency, packet dropping/corruption and other aspects. We shall use it in order 

WANem is distributed in the form of a bootable CD with Linux Knoppix O/S. A VM appliance is available for download.

We shall connect the two machines using deltaShaper through WANem in order to test the system in varying network settings. 

==== Using WANem ====
  * Boot the VM image
  * Create perc user for remote connection
  * Configure network devices (Either statically or DHCP)
  * Configure other devices to route their traffic through the WANEm VM.
  * Access http://WANEM_machine_IP/WANem to control WANem through GUI

==== Linux Routing ====
We can route the traffic of the machines using our video-conferencing tool to go through the WANem VM:
  
  #route all traffic through a given machine
  route add default gw 146.193.41.207 eth0
  
  #route the traffic for a single host through a given machine
  route add –host 192.168.140.12 netmask 0.0.0.0 gw 192.168.140.20
