How to give access to virtual machines in esxi 6.7 to an external network?

Question

System administration

Found a course in ESXI, assembled a training stand on Vmware Workstation. Consists of: one ESXI 6.7 server and Server 2012R2 (works as DHCP and from it I go to the ESXI webmord). Everything was fine until I got to the stage of setting up the vCenter server Appliance. While I was sorting through the options and trying to understand what the problem was (at the last stage, the installer wrote that it could not connect to the VM), it turned out that the VM simply did not have access to the external network. Inside ESXI itself, they see each other (ESXI pings vCenter and vice versa), apparently the network configuration step is cut out of the course. I tried to find material on the net, but I could not find anything I needed. I understand that the question is most likely simple, but I can not find a way out of the situation.
I would be grateful for any hints.

The question is closed.
The problem was that I had to enable Promisc Mode in ESXI. But turning it on had no effect. As it turned out, VMware Workstation did not allow it to be enabled on the virtual adapter (vmnet1), since to enable this mode, Workstation must be started as root. In my case, the command helped:
# sudo chmod a+rw /dev/vmnet0
