DNS registration request by Server to AD/Domain Controller. Will the source ip will also change.

There is a F5 LB sitting I between a web server and the DNS server. The web server has a static IP 17.168.1.10 configured on the NIC. The F5 LB is natting the physical IP to 10.1.1.10 and the clients use this IP to access the web server.

Now the problem. When the web server registers its IP in the DNS, it is registering the physical IP 172.168.1.10 and not 10.1.1.10 Can you suggest a way to correct this issue?
