1Gb internet connection

[taofineberg]

I am looking at a requirement for a client
They are going to be installing a 1Gb internet connection.
The interface that the ISP will install is a ST single mode fiber.
They are going to be setting up 4 VPN tunnels to their different data centers.

Are you able to provide a spec for what type of router and interface they require.
