  • 1.  Bridge VM only possible with vDS or promiscuous mode?

    Posted Mar 25, 2021 08:47 AM

    For a client project we need to set up a VM which acts as a network bridge for other VMs on ESXi hosts. Due to the way the normal vSwitch works the traffic for other VMs is being dropped.

    To make this work we need a virtual switch that supports MAC learning + forged transit. We have set up a demo using a vDS switch that supports this and it's working. However, the licensing cost for vDS seems prohibitive as either Enterprise Plus or vSAN license is needed.

    We found as an alternative it is possible to enable promiscuous mode on a normal vSwitch, this works also, but this brings additional traffic and security issues that are not acceptable.

    Is there any other way to this to work?

    Hery, how are you?
    Can you attach screenshots of the NICs and how you have them configured?

    I can't access the VM stack at the moment, but I put in the attached diagram how it's configured, I hope it's clear enough.
