I was actually working on server-client software in Go to allow multihoming IP connections.[0] The original use case was to load-balance packets across wi-fi + 3G or other connections. It's not quite user-friendly yet, but with a little work it could use new connections as they come up (maybe poll ifconfig?). You'd of course need to install the software on your outside server that will forward packets for you, but a DO droplet would be great for that. It'd also work for the case where your router is your server and you shift between wired and wireless. [0] https://github.com/erjiang/tuntuntun https://github.com/erjiang/tuntuntun
