ICE configuration

My question is about best practices when it comes to enabling ICE. Cisco documentation is really lacking in this department.

I have a straightforward design: VCS-E in the DMZ, VCS-C on the inside, with endpoints and MOVI connecting both on the inside (internal users) and outside (home users behind their home firewalls). VCS-E has TURN enabled.

Home users ----  Internet  ------- FW ------ VCS-C -----local users

                                    |

                              VCS Expressway

                                                      

The question is what's is the right way to set up ICE to provide best media routing for all users?

As far as enabling ICE on VCS-E, which zones do need ICE enabled? Default Zone, DefaultSubzone, DNS Zone?  Do I need to enable ICE on the TraversalZone to the VCS-C?

Do I need to enable ICE on VCS-C at all and if so on which zones?

What should I set Default Media Candidate and Public Media Candidate for MOVI users?  Is it Host and Relay respectively?

Same question for C20 Endpoints.  Should I set it to Relay for external endpoints and turn ICE off for internal endpoints?

Any enlightenment would be appreciated.

Thanks,

Eli

Hi @Eli Kagan ,
What was your finding?
I'm looking for recommendation on best setting for source to be Host or Relay?
