understanding site to site vpn's

I need help understanding site to site vpn's. When a site to site vpn is established is the connection always active or does the user have to execute a program to connect to the other site. And if the user connects to the other site, how does the connection not get confused  with their present network. Help me understand, I am new to this.  :0)  All feedback is appreciated.

Oops, my text-based formatting didn't come through on the post, but hopefully you get the idea.  I'd intended for the ends of the VPN tunnel link to show up directly in the middle of each of the VPN firewalls.

good answer. Have you heard of any successful connections using the sonicwall pro4060 and a cisco pix?
Glad to help.
Haven't yet configured a VPN between the two, but I imagine you should be able to. Sonicwall's website has this doc that may hellp:

calvinetter,
You seem very knowledgable in this and I'm also a newb and have a question if its ok.
In your response you wrote:
"  LAN A: IP range = 10.3.2.0/255.255.255.0
   LAN B: IP range = 172.18.0.0/255.255.0.0  "
My question is, do LAN A and LAN B have to be on different subnet masks and can they both use say 192.168.1.x or do the IPs have to be different?
