Windows DNS Update with Lease Pool Address

As soon as an APM tunnel is established, I want to update our Windows DNS server with the Lease Pool IP address assigned to the session. In the Network Access List I have checked “Register this connection's addresses in DNS”. In order for this to work do I simply need to configure a NTLM Machine Account on the Big-IP and in AD create a computer object with a DNSUpdateProxy group so that it can do a DNS registration on behalf of the client?

Thanks.
