Best way to setup VPN network? (small office)

I posted a while ago here about our problems with email/VPN, and we did go with a new provider (sonic.net) which has been better. That was a great suggestion.

However, we are still having VPN issues, and this has wasted quite a few hours/days for everyone here in our SF office. Unfortunately, I don't know much about VPN at all (except that it doesn't work most of the time here), and I am getting very frustrated with this whole process. Our IT consultant guy out there insists that it's our SF Linksys wireless router that is having difficulty communicating with the D-Link router out East and that a 'good' solution is to get a D-link router over here too. :roll:

Instead, I would really appreciate any suggestions on a good solid router/etc. configuration to make sure that we will *never* have these, um, fun, VPN/connectivity problems anymore. In SF we would like to have a wireless router that also can distribute our 8 static IP's (ideally, dynamically), and either a wireless or a regular router in NJ. I heard that putting Sonicwall routers on both ends would do the trick. What do ya'll think? Are there other solutions we should try?

Summary:
- desperately need a solid/permanent VPN connection b/w two offices (and a good on-call IT guy in SF, haha)
- 10-15 people in SF, both wireless or wired in
- 20-25 people in NJ, usually wired in although wireless could be good
- Windows VPN client
- Both SF and NJ on DSL
- Currently D-Link in NJ, Linksys WRT54G in SF (this really shouldn't matter)
 
Though I've never set this up either, it's a solution we've sought out also. It's interesting that you mention SonicWall because when we got a professional quote to setup a permanent VPN connection between two offices, they suggested a couple of $800 sonicwall firewall/VPN endpoints on each end and have them tunnel to each other. Now I'm not really sure how this works or how to set it up, but I think that's the main idea of it. Maybe someone can explain more (it looks like just a bunch of tweaking settings here and there so that the two firewall/VPN boxes can directly connect to each other.
 
My understanding is that the SonicWall routers establish a single 'permanent' VPN connection, and everyone in the office can log on just like a LAN. This makes sense, but is it the best, most reliable solution out there?
 
I'm not sure how you even have VPN working with those two routers right now being as they are both VPN passthrough only. As far as I know in order for the networks to be merged together both of the routers need to be VPN Endpoints. Kind of like this:

..............<<Internet>>
......................||
.......[Linksys WRT54g Router]
.........|...........|...................|
[PC #1]....[PC #2]....[Network Printer]

1. VPN Endpoints connect both routers together. As you can see above this would allow each network to see the entire contents of the other, including the printer and whatever else may be hooked up.
2. VPN Passthrough allows VPN connections to pass through the router to a PC inside the network. This isn't as good as the PC may not have access to the contents of the rest of the network. And a PC is a lot more flakey of an endpoint then a quality firewall that would be on 24/7.

As far as Sonicwalls go I have been looking at them for an office of my own. (One of the SOHO series.) I haven't bought one yet but people seem to think that they are good. If anyone has more suggestions for good firewall/VPNs I would appreciate the input. 🙂

This is all based on my limited understanding of VPN. Please correct me if I am wrong. 🙂

hmm, ours currently looks more like this:

[PC #1]....[PC #2]....[Network Printer]
.........|...........|...........|...........
.......[D-Link Router in NJ]
......................||
..............<<Internet>> and VPN conx
......................||
.......[Linksys WRT54g Router] (SF)
.........|...........|...................|
[PC #1]....[PC #2]....[Network Printer]

+ local servers on both ends, web server in NJ
