Client Registering with DNS - VPN Client

I am using a Cisco VPN Concentrator and a Windows XP workstation. I have

created a "wide open" profile on the concentrator to allow me to log onto my domain over

the tunnel and access all my resources locally. The profile is wide open, and split

tunnelling is not enabled, so all traffic is routed over the tunnel while established.

This works very well.

However, the VPN Client PC gets an Ip from the ISP. When I log onto the machine and it

registers on my domain, the VPN Client assigns an address. In my DNS at the main campus,

the workstation gets registered in DNS with both IP's. The ISP is not valid (the

192.168.254.1) because I do not route that addess, nor do I want too.

See below....

U:\>ipconfig

> Windows IP Configuration

>

> Ethernet adapter Local Area Connection:

> Connection-specific DNS Suffix . : domain.invalid

> IP Address. . . . . . . . . . . . : 192.168.254.1

> Subnet Mask . . . . . . . . . . . : 255.255.255.0

> Default Gateway . . . . . . . . . :

> Default Gateway . . . . . . . . . : 192.168.52.1

> U:\>nslookup testremote

> Server: jupiter.bcne-master1.bcne

> Address: 10.201.8.20

>

> Name: testremote.bcne-master1.bcne

> Addresses: 192.168.254.1, 192.168.52.16

So only the 192.168.52.16 is valid, the other isn't routed. How do I prevent this

behavior, either on the concentrator, on the client, or on the domain. I do not want both

addresses registered.

Thanks

Re: Client Registering with DNS - VPN Client

You can configure the vpn client to not to route the traffic with source IP assigned by the ISP via the vpn tunnel. Following link may help you
