Persistent VPN Tunnel

I need to set up a persistent vpn tunnel between headquarters, using a sonicwall 3060 Pro with a public IP address and a remote office with about 10 users, which has dsl for internet.  I don't know what kind of hardware I will put in the remote office, but do I need to ask the dsl provider for a static public IP, or is there a way to set it up just from the remote end and keep it connected???

you can use dsl with non-static ip address. i'd recommend using sonicwall in the remote office

Can you give me a some detail on how you went about doing this???
configuring vpn tunnels, on main box for particular tunnel you configure it with aggressive mode (not main mode) and configure with unique identity string by which your main box validates the remote site.
on the remote site, when configuring vpn you also configure aggressive mode, configure ip of the main box and the same identity string.
