LAN to LAN Connection issue over VPN
My company owner has a small 4 computer network at his house that is all connected together with a linksys hub and then the linksys hub is connected to a linksys router/firewall that is then connected to a DSL Modem. He uses VPN to connect to our office so he can check up on things via remote Desktop Connection, and his wife uses VPN to connect to the office so she can Connect to our Exchange server to use outlook 2003 for emailing and etc.
So, the problem is that only one of them can connnect via VPN at once. The other problem, and the biggest pain is that when one of them is done with using the VPN connection, and the spouse then wants to use the VPN Connection on her computer (her computer is in one room and his is in his office. Both connected to the hub via CAT5) They have to power the router off then back on or else they have issues with the VPN connection.
The problem that occurs is that when one of them disconnects, and the other connects, then the VPN goes through it's motions like it is actually connected, then it shows the system tray icon like it is connected, but the VPN on the office side for some reason, thinks that it is still the other computer connected. They want a soloution yesterday and I am out of ideas. The only thing that I can determine is that I have to figure out a way to get their linksys router to transmit a unique IP address for each machine each time they connnect via vpn.
If you can help me, I'll dance a jig at you're wedding....

Sounds like they are using a router that does not support multiple VPN connects...I know that is an issue with the lower end routers.....
What is the model of router you\they are using???
Get them a new router that supports multiple VPN connections
Google has lots of info on it

Thanks MLF. I appreciate the help. I'm requesting his model number and firmware version. Chances are, I will just have to upgrade the router. Too bad Christmas bonuses were already passed out. I'll be the hero to fix this one.

Indeed this is the case. The low end/old D-Link and LinkSys routers are notorious for this. They cannot handle the connection tables properly is the specific issue with the old LinkSys routers.
PS
Updating the firmware may not solve the issue depending upon how old the router is. I'd be interested to know how this little project concludes. Please post an update here.

I currently have a small office to small office IPSec connection that's been working very well. It's just two old 333 Mhz boxes that are running IPCop on them. I've had some problems, but it's mainly because one of the offices has a terrible internet connection. I've had more reliable dialup.
If you get a couple machines with a bit more horsepower you can mod the IPCop install to have all sorts of nifty features. It's just a suggestion, I've had decent luck with it.

Looks like a firmware upgrade may fix the issue.
There are several vpn related protocals listed there as being resolved.
Resolves issue with PPTP passthrough
Added L2TP option for WAN connection type
Resolved issue with L2TP disconnect
Thats just at a glance though... You didn't really say what kind of vpn you're running.
Firmware&Config are the first things you should look at.

Hey Hey,
I'll post something that I've posted time and time again... just to hammer the point home.
3rd Party Firmware -- http://www.sveasoft.com/content/view/20/1/
Specifically the Talisman VPN version
Peace,

HT: I've been using sveasoft firmware for sometime now. I've not tried the VPN one though... I've just been using basic. That has been pretty stable and I've had no issues using a VPN. But then again... I'm the only one trying to connect at one time.
You can find the basic versions in the link below for free.
I beleive you have to pay for the more specialized versions that HT posted.
http://wrt54g.thermoman.de/
But watch out... The older wrt54g routers are not supported. I beleive its version 2 and above.
With such old firmware still on the router (2.x.x), you probably have a very old wrt54g.
Just make sure you have the right hardware before you load the firmware or you'll foobar your router.
