TeamViewer is a free tool that makes it incredibly easy to set and use a VPN connection; a Virtual Private Network that lets you take complete control of another PC from your own computer, whether they're separated by a soda can or a continent (and as long as both machines are running TeamViewer). It enables two-way connections in which users can flip control back and forth. TeamViewer also lets you hold virtual meetings with multiple participants (again, they all must have TeamViewer installed). With a name like TeamViewer, you'd expect it to be an enterprise-ready tool, and you'd be right: TeamViewer's robust simplicity is what happens when multiple users of vastly different skills need to use software. After a while, the bugs get squashed pretty firmly. But TeamViewer is free to non-commercial users. That means you can use it to access your work and home PCs remotely, of course. But you can also install it on your mom's PC (for example) and provide tech support from home.
Logmein or Teamviewer? (2009)
The computer that is acting as the server, does it have Windows Firewall (or equivalent) turned on, and is that also got the VPN port open?
For IP address, I'd suggest you get a static IP at home, then setup a domain name to point to it, such as home.mycompany.co.nz, and enter this as your server address.
With a VPN, you need to pull the large file across the connection before any processing can be done to it. I know most myob biz basics files are about 20-50mb.
Anyhow with a remote desktop, the processing is done on the remote computer, and a picture of the result is sent across the link. For older programs that dont use any modern database system like sql and they talk to the file directly, it can be a time consuming process working over a vpn. Remote desktop is much better suited for this.
Basically the VPN transfers your whole company file across the -slow- and -expensive- link to your client computer, just to process a quick and simple query.
The remote desktop (RDP) or teamviewer / logmein will run the program on the remote computer, and allow you to control it. It only sends keystrokes and mouse movements back to your office computer, and that inturn just sends back small images. It also can cache commonly used images such as a picture of your start menu or desktop to save on bandwidth. A more common system of this is called a Terminal Server - I administer about 200 workstations that log into servers (in a similar way to yours) to access a company database application. It uses very little bandwidth because of the screen image caching and database files themselves do not need to be sent to remote clients - Just pictures of the program.
Teamviewer as you have found will work very well. I use it to administer remote workstations for some of my smaller business customers.
You are not doing anything wrong with a VPN, its just slow and expensive and the teamviewer gives you the same end result, with less bandwidth used and its faster.
Your next issue that you may encounter will be printing.
You can easily print with the program running locally on your laptop and accessing the file via the vpn. The local program will generate the print and send it to an attached printer just like any other program on your laptop.
With teamviewer, the program is running on the remote computer / server and so it doesnt see your local printer as attached to the pc. To get around this, you will need to install a program called PDF Creator and email printouts to your local pc from the server computer, or investigate something called microsoft remote desktop which works similar to teamviewer but when you connect to a server computer, your local printers are added and print jobs are sent virtually through the remote desktop connection. Microsoft remote desktop is built into XP Pro and upper versions of vista and win7. The client program is built into xp home/pro/all vista and all 7.
You can use Remote Desktop as suggested - but you will need to configure a port forward on your router. I use Logmein in some of my PCs at home. It requires no port configuration. You can remote access/control your PC without having to configure shares, firewall, etc.
Hamachi is a VPN and you will have FILE access. I suggested Logmein, which is the remote access and you will have remote control of the PC - very different things.
I'd agree your VPN issue is most likely to be related to the IP address or perhaps a firewall issue, VPN hosts really need a fixed IP address to simplify day to day usage / management.
For client support/access I use a mix of VPN, Microsoft Remote Desktop and Teamviewer depending on the client.
I've found I can achieve the most consistently reliable connections both within NZ and NZ/Australia using Teamviewer & Remote Desktop.
While my VPN connection does work reasonable well most of the time, I've often experienced brief dropouts which have caused corrupt files etc.
I often connect to a client in country Victoria and they use a Satellite/Dial-up hybrid connection which has good download but very poor upload and despite that it still is quite usable with Teamviewer (it will not work using a VPN).
Maybe a dumb response, but is the router suitable for VPN ?
The other thing that springs to mind is that I make sure that ports TCP 1723, UDP 500, 10701 are open.
Rather than doing the port forwarding yourself by using port 1723 does the modem have a list of applications that you can just choose and it does all the port forwarding for you?
If it does look for VPN or PPTP and select that.
As pointed out in an earlier post PPTP VPN does require more than just port 1723 to be forwarded, the router also needs to support VPN passthrough.
