Has anyone done anything for a firewall that can take UDP packets, stuff
them into TCP packets addressed to a specific UDP relay socket address
and then unstuff them at the other end?
Or is this idea no better than simply opening up a range of UDP ports and
just filtering out IP addresses that you don't want to let through?
