I bring my own router

Today I needed to work from a coffee shop since my cable modem went on the fritz last night.  I use virtual box to virtualize a Kazoo cluster on my laptop with 10 linux servers.  I kicked around a complicated NAT’ing scheme for port range forwarding, but I wanted to keep things simple at the networking level at the early stage in the game of the testing some new feature development.  So, instead of changing 10 static IP configurations, I brought my own router.
