Cisco 3750 as DNS Proxy

I have an environment where I install a bunch of servers before I ship them out to a customer.  At the customer site I have a DNS server of And a subnet of

In my environment here, I have a corporate DNS server at

All of the servers that I install here are plugged into a Cisco 3750 that has a route to our corporate network.  I have VLAN2 on my 3750 configured with the customer subnet of  I would like to configure all of my servers wtih the DNS ip address that they will have in production.  This means I would need the 3750 to act sort of as a proxy DNS. The servers would send DNS to the 3750 who would then forward it on to the corporate DNS server.

Is this something that is possible on 3750s?


Re: Cisco 3750 as DNS Proxy

NAT would be a solution, but it is not supported on the 3750. Could you build a cache-only DNS server and put it in VLAN 2?
