VPN to SBS 2011 Server

Hi,

My client is having problems connecting to the head office VPN.

I have tested their logon credentials at our office and it works fine

We have even tested our server VPN settings at the site that has the problem and that connects ok so it can't be the laptop or the router.

They are trying to connect from home and they have a techni color router.

I am confused, any ideas?

Hi Ryan,

What is the IP Range at home?  Presuming its not the same as the one in the office?  If so you will have trouble.

Thanks,

Just to confirm, are you using the SBS for the VPNs or is it being done via the Router?

How many users do you have using the VPN at any one time?  By default SBS2011 allows 5.

When trying to form the VPN does it give you an error regarding credentials?

Have you given the user VPN Access roghts via the SBS Console?

Can you read the logs on the vpn server?

Can you try the laptop in a different remote location?  (friend, coffee shop). The firmware on the user's home router may need upgrading.

Also, make sure the user's ISP allows VPN packets.

Hi All

This VPN was working ok last week

They are using routing and remote access on SBS2011 - only 2 people use the VPN at any one time.

We are receiving error 806 - it mentions something about GRE Protocol Port 47 (when I check the event viewer on the sbs server it doesn't show anything)

Nothing has changed at the server end or the clients end.

I will get the client to test the vpn outside of his house.

Thanks
Ryan

As I say it's has been working and nothing has changed. So yes all the ports are open.  

The vpn works from my office!

Did they change / reset any of their router setting?

Is vpn passthrough enabled?

Nothing has been changed. From his home address I can VPN To our server at the office so there is no outgoing Issue.

I can then dial into the SBS server that they are trying to dial into so there is no issue at the server end.

Ie. There is no issue with outgoing connections nor issues with connecting to the server.

Try is (as you said you would) from a different location.

Another thing you could try is removing their remote access rights and re-adding them again.

The ISP fixed this issue, they reset the router from their end.
