How to change the IP address to give to PPTP clients

[Bo Berglund]

I have a Win2003 server running as a VirtualServer 2005 guest with the
single task of providing PPTP VPN tunneling into my internal network.
It was set up years ago and has a range of IP addresses for the
connected clients in the 192.168.1.xxx subnet.

Now for reasons of changing ISP and getting a new ADSL modem/router I
have to change the internal addresses from 192.168.0.xxx to
192.168.1.xxx, basically setting the 3rd octet to 1 instead of 0.

I have looked at the RRAS management console but I could not find how
this can be accomplished at all. I simply cannot find any editing of
the range at all. :-(

Can someone here please guide me to the correct place in the
configuration where I can modify the addresses????

How is the RRAS configured to provide IP. if you use an internal DHCP
server to serve IP addresses the you might have to make a change
there. If you are using the the static pool of IP addresses to be
assigned to the VPN clients then you can

1. right click on the VPN server in the RRAS management console
2. Click on Properties
3. Select the IP tab
4. Edit the Static IP Pool assigned for VPN clients

Hope this helps
