RRAS PPTP server and different static address pool subnet

Hi,

I'm running af RRAS on a Windows 2003 SP2 (VMWare) member server. The RRAS servers network configuration look like this:

192.168.0.198
255.255.255.0
192.168.0.2
DNS 1: 192.168.0.7
DNS 2: 192.168.0.15

I have setup RRAS so I have Demand.dial VPN connection to a remote office and that works without any problems. Also if set IP address assignment to DHCP or Static address pool, my PPTP user clients can connect and access the network.

The problem is that the business network is 192.168.0.0 and many home network also have 192.168.0.0. It’s not possible for us and change the business atm. So instead I will set the IP address assignment to a static address pool and a range of: 172.16.25.20-172.16.25.45.
If I do so the PPTP client get the correct IP fx 172.16.25.20 but are not able to connect to business network 192.168.0.0 and access the Internet/WAN.

I properly need to add some routes but can someone tell me where? PPTP clients must also be able to connect to another remote office that has a network of: 192.168.2.0.

The RRAS server is behind a firewall and I have NAT PPTP and L2TP ports and GRE protocol (however if clients try and connect with L2TP they are unable to connect).


Thank you.
Kristian

So the RRAS server is not the default gateway for the machines on the network? Then you must add a route to tell them where they can find the 172.16.25.20-172.16.25.45 network (through the 192.168.0.198).
If the machines are on dhcp you can do it through there. Otherwise sut it up manually.

Also make sure IP routing is enabled on the RRAS server.

Do you then know about L2TP issue? I could make a new question.

Glad I could help.

We could always have a look at the L2TP issue and see what we can do.
