It sounds like you are looking for a travel router that supports VPN connections for your tablet and laptop. You can use either of these approaches:

• A router that itself supports VPN connections, so that you can share its VPN connection with your tablet and laptop
• Software on your tablet and laptop that creates VPN connections over a router or any other Internet connection

I would first investigate VPN software for your tablet and laptop, because this is useful with or without a router. If you need to share an Internet connection between your tablet and laptop, you can use a travel router and still use the VPN software on your tablet and laptop.
