Re: VPN Router selection If you want an off the shelf solution, I would go with the USG50. It gives you more VPN sessions and additional head room for the future.
Today you have two stores with a possible 3rd in the near future. That will max the VPN capabilities of the USG20.
You could build your own device, ie a ASUS RT-N16 using DD-WRT or build a PFSense, possibly atom mini-itx based system.
Another alternative is a device such as a Microtik RB750GL. It is very powerful and flexible but you will need to understand networking and be comfortable with using a command line to provision.
Also, use an external switch. The Zyxel GS-1100, a 16 port Ge switch, keeps popping up on sale. It was on sale just a few days ago for $60. I purchased a second one. It is currently $90 on NewEgg. »www.newegg.com/Product/Product.a···33181152
