Can I use CISCO 827 for VPN server?

[melospawn]

Hi, I need to make a VPN with 5 offices around Spain via ADSL. I know that cisco 827 can handle VPN, but, will I need a VPN server like cisco 3000 to handle all?, or will I be able to use some kind of software with windows 2000 server to be the VPN server? Or can I use router 827 to be the server?.
I know that 7100 and 1700 routers and PIX 515 can be VPN servers.

Thansk a lot for your time

You can create GRE tunnels in the default feature set. Just go to config, interface t0, give it a tunnel source ip address (the dialer ip works fine), a destination ip address (the partner's dialer's ip address), then go to general config and create a route to go to the inside IP range at the other end and specify tunnel 0 as the port. do the same thing in reverse on the other router and you've got a VPN. If you need additional meshing, just create tunnels 1,2,3,4 for each additional pair of sites.
