Hi,

 

I found this information internally, let me know if it fits your request :

 

  • HTTP explicit proxy Virtual Server is configured with DNS Resolver (in HTTP profile) with same destination ip address as another (DNS) Virtual Server created to process DNS requests and forward them to the DNS server (pool member) on the same BigIP system, DNS Virtual Server needs to have Source address translation enabled to avoid using loopback address when initializing connection towards the DNS server (pool member). When Source Address translation is disabled, when receiving traffic initialized from loopback address, DNS server is not able to respond.

When you set the proxy mode to Explicit, you must also configure the settings in the Explicit Proxy area of the HTTP profile.

 

Else, if does not work, please open a support case in order to check if RD is supported.
