firewall ports – TCP / UDP

  • -posted on behalf of Saravanan M.

    We are trying to open firewall ports for VMware environments. There is a requirement to open port 22 (Required between an ESXi host and the ZVM during the installation of a VRA). is this 22/tcp or 22/udp or both? if it is UDP could you please let us know why UDP protocol is required for this?


    This is Contara from Zerto Support. Just open port 22 TCP.  Not UDP.

    The following table provides basic information about the ports using in Zerto Virtual Replication.
