Hi, I would like to know the best design .
We have existing on-premises platform in green zone for internal partners, would like to use same platform for external partners as well, by logically separating by organization level. To use the same platform for external partners, what is the best design? External firewall, DMZ zone and Internal Firewall approach? what is needed in DMZ zone? do we need to install any components like Router and MP additionally in DMZ zone? how to use DNS in DMZ zone? need detailed explanation on the setup.
