Can someone explain to me the implications of static v. dynamic IP addresses on broadband satellite solutions? Also, I know there is an issue with running a "tunnel within a tunnel" but don't fully comprehend the reasons behind it. Are these two issues interrelated? The land-based transmitter/receiver in a satellite connection actually uses a VPN to tunnel into the internet? And because of this one cannot run a VPN across a two-way satellite connection ie.., a tunnel within a tunnel?
