Where does the ACS server get the DNS info for IP pools?

[randyclark]

I am trying to change the DNS servers that my VPN users are assigned from the IP pools on the ACS server. Where does the IP pools get the DNS server information. I have changed the DNS Ips on the windows server and rebooted. But the VPN clients are still being assigned the old DNS servers.

ACS ip pools do not push DNS server information

It is either being forwarded from VPN concentrator group setup or

it is being send from ACS user/group setup > Radius(VPN 3000) attributes > [026/3076/005] Primary-DNS.

Hope this helps.

Regards

Rohit

Yes I forgot about the groups on the concentrator. That's were it was assigned. We started using the VPN without the ACS and the DNS was still in the group.
