Do I need Public CA to B2B Deployment?

[reyesclaudio]

Hello, 

In the deployment B2B, Do I need public root CA for the certificates of EXP E to communicate with other companies?

Regards.

That depends whether you want the connection TLS or MTLS encrypted and whether the far end is willing to install your private CA chain.

Thanks you Jon, 

I am trying to understand. If I want coneccion with TLS, I need to install de CA from Federation and viceversa?

What happend if a want to deploy 3-port Firewall DMZ Using Single Expressway-E LAN Interface? In this case I do not need to share certificates with any one right? Just con my Private CA.

Thank you for your answer, I do not know why my notiifications is disable.
