psb Posted April 12, 2008 Share Posted April 12, 2008 (edited) Hi all,I've configured VPN access on SBS 2003 R2 and have downloaded the Connection Manager to the client PC (Thinkpad - XP Pro).When I click to connect to the VPN, I enter the username and password and am able to successfully connect to the server. The client PC is showing as connected to the SBS network.However, I am unable to use any of the resources on the server. I cannot access files or folders. Any ideas why this is happening and how I might fix it?Many thanks! Edited April 12, 2008 by psb Link to comment Share on other sites More sharing options...
Mijzelf Posted April 12, 2008 Share Posted April 12, 2008 Standard pitfall when using VPN: the subnet of the VPN *must* be different of the subnet of the LAN. Link to comment Share on other sites More sharing options...
psb Posted April 12, 2008 Author Share Posted April 12, 2008 (edited) Thanks for that... how do I do it? I've also discovered something else. If I access the internet via dial-up, I am able to successfully connect to the server via VPN AND access everything on it... but access via broadband (wireless or ethernet from a different location), the VPN successfully connects but nothing is available. This is strange!Any help would be very much appreciated Edited April 12, 2008 by psb Link to comment Share on other sites More sharing options...
nmX.Memnoch Posted April 12, 2008 Share Posted April 12, 2008 When you access the VPN through broadband are you connecting through a Cable/DSL router? If so, you may need to enable that traffic to pass through. On a Linksys router go to Security > VPN and enable all three options. Link to comment Share on other sites More sharing options...
psb Posted April 13, 2008 Author Share Posted April 13, 2008 Yes, I'm connecting via a router. So does this mean that if the client PC is working remotely, the router is uses will have to have ports open to allow VPN? It's quite obvious when you think about it, but I hadn't really considered beyond my current network and assumed it would function. Link to comment Share on other sites More sharing options...
nmX.Memnoch Posted April 13, 2008 Share Posted April 13, 2008 For it to work properly, yes. Most decent home routers have an option to enable or disable VPN passthrough though. Link to comment Share on other sites More sharing options...
Mijzelf Posted April 13, 2008 Share Posted April 13, 2008 Thanks for that... how do I do it?In most cases you can't change the subnet of the VPN. To change the subnet of the LAN, use a browser to open the router setup screen, (use the 'default gateway' address), and search for DHCP server settings. It will probably give addresses in the 10.0.0.x range, or 192.168.0.x range. Change that to 10.0.1.x or 192.168.1.x or something like that.
