Thanks Ram,
I think this can be very useful from a support perspective. I am familiar with dynamips/dynagen/gns3, but being able to run other virtual machines in the lab is very convenient.
We will definitely take a look into UNL at some stage. Would be interesting to see if a switch can be added at each site and the Wanos lan0 removed. With the PC, Wanos wan0 and router connecting to the same switch, it should be possible to enable router mode as well.
Great idea, thanks!
