VPDN and DNS suffix.

I have asked this question in a few forums and no one replies, hopefully i can get help here.

I have configured VPDN using radius authentication for remote users who dial in to a local ISP. I have configured the LNS router to supply the ip address and DNS addresses requested by bootp from the clients using the following commands:

- ip local pool <name> x.x.x.x x.x.x.x

- async-bootp dns-server y.y.y.y

The problem is that i don't know how to send the connection-specific DNS suffix. When i type "ipconfig /all" on the remote PC i see all the addresses under the PPP adapter but obviously no suffix.

Has anyone done this or know how i can send the suffix either by the router or Radius server that authenticates the users.

You have just do to this in router config:

ip dhcp pool PPTP

  network X.X.X.X /24

  domain-name YOUR-SUFFIX

  dns-server X.X.X.X

interface virtual-template 1

  peer default ip address dhcp-pool PPTP

And erase previous config:

no ip local pool name x.x.x.x x.x.x.x

interface virtual-template 1

no peer default ip address pool name
