Firewall Bridge inside one ESX

[NaArea]

Good Afternoon,

I need a little help in a complex medium scenario at least for me.

I have an ESXi Installed with 8 physical NICs and I'm using some for other servers.

I need to install a firewall bridge to connect a router to my LAN, then thefollowing scenario:

  VSwitch1 named INTERNAL LAN with a dedicated network adapter
  VSwitch2 named EXTERNAL LAN with a dedicated network adapter

I installed a Linux and configured it to work on bridge and added two network cards,each adapter is in a VSwtich.

Theoretically it should be working, because it is a  identical scenario  today, but with a physical machine. When I try to put it on, it simply does not allow packets to pass through one of the Ethernets.

How can I run the firewall within a bridge in ESXi?

Ever I tried to find  information about  bridge in vmware, most of them isn't about  firewall in bridge.

Thanks.

I have used PFsense for both physical and virtual routers for several years (free but excellent commercial support is available). It is very small and easily configured from command line or web gui.

My Firewall is working, the problem was a configuration of VMware.
It was the only change to accept two VSwtich promiscuous mode is ready, everything working.

Thanks
