VPN - Static / Dynamic

By RowdySH ·
Hi there,

I am completey stumped.

I have configured a VPN using RRAS on Windows 2000 Server. The RRAS server provides a DHCP address to the connecting client. The VPN is accessed through a static IP address.

Once the person logs in they then have access to 2 different internal ranges through the creation of a static route: range and a range.

Here's whats troubling me:

I have tested this with dial-up modem, and from a permanent public IP address with no problems ie, I can access both ranges through the use of static routing in RRAS as well. However on my cable internet at home which has a dynamic IP I can only connect to the range, and the other range simply times out. The only other thing I can think of is at home I also have RRAS setup on Windows 2003 for Internet sharing and also assigning IP address to my machines.

Any ideas? I don't think it's operating system specific for the client as I've successfuly connected via XP Pro and also Windows 2003 Enterprise Edition.

It's got me stumped!

Let me know If I haven't explained something clearly enough.

Are you using any firewalls or internet protection devices that may be stopping the connection?

I know that with Norton Internet Security you have to set up a range of IP addresses that is allowed for the VPN Connection to work.

What is your IP range at home? If it is the same subnet as you are trying to access on the VPN, then that's the problem.

do a tracert from your home computer to your rras server at work. then do a tracert from the rras server at work to your home computer

this should tell you at what device(s) the packets get dropped. then you can troubleshoot from there
