VSX - Virtual System NAT behind a Virtual Router IP?

Good afternoon everyone!

We are working with a customer with a high number of Virtual Systems in a VSX Cluster. One request is that all DNS requests go out a single interface to a specific server.

The plan was to use a Virtual Router for all the VSs, however we ran into an addressing issue. Now, from what we have 'googled', a Virtual Rouger does not support NAT, although through testing we noticed we can actually replace a VR policy for your own (tested to respond to ping).

Is it possible to have a Virtual Router do Hide NAT to an external IP? If not, any recommendations on how we could pull this off (other than just creating 100+ addresses and routing to the VR)?

 

Thanks!

As far as I know, virtual routers don’t do NAT.
Why not just create a VS that does this?

This system is already up to 150 VSs, so I am just trying to optimize on the processing wherever possible, but it might be the only way...

Dunno that a virtual router is any less processing than a VS, particularly one that would be firewall only.
