Return a Public IP to DNS query and send traffic to RFC1918

I created a WIP that I'd like when queried outside, it shows a public IP, but forward traffic to RFC1918 VIP. I created a NAT instance under delivery, but it doesn't work.

Hi,

 

A WIP doesn't perform forwarding to a virtual server. It only answers with the DNS query with the correct IP address.

 

Natting of your public ip to RFC1918 should be done by a firewall (or BIG-IP).

 

Having RFC1918 address on your virtual servers and WIP serving public IP can be done by creating a dummy virtual server with the public IP address and use this virtual server in your wide ip pool.

 

Cheers,
