Make a virtual WAN for software testing - Linux

I am in the process of writing a socket program that will need to talk to different computers across the world. I want to set up a virtualized WAN on my computer so I can install the software on a virtual machine and test it's connectivity in a "real"ish WAN environment.

http://wanem.sourceforge.net/ Looks promising for setting up the WAN, but I was curious if anybody knew a better way to do it than setting up a bunch of virtual servers, and then another virtual server running WANEM to act as the WAN. I have never been very successful with Virtual Nic's.

Not a great option - but if you have a few extra machines around, you can always physically set one up. I think we can all agree that's a gross option. I'd personally go with VMs, but yeah, I get that too can be weird for networking. +1 - interesting question. – James T Snell – 2011-07-13T17:51:38.857

Depends on what facet of the WAN you are trying to emulate. If you're using vmware then you can set up the hosts on a virtual LAN segment and then throttle the bandwidth and specify the packet loss over that LAN segment. wanem gives you the ability to control the latency as well.

Did not know that about VMWare I have been using virtual box, I will leave this open for a bit to see if anybody comes up with something really interesting, then make yours the answer – Chris – 2011-07-15T19:02:01.097
