Hey,
I missed a line in the config. You have DHCP snooping turned on it seems. Can we turn that off?
System > Services > Global Configuration > Turn it off
Cheers
Again, would have thought the global config setting it off would be sufficient (screenshot top line) but happy to try:)
It is odd. It seems enabled in the config file.
I will PM you. I might have support look into this.
Ok, I think something helped finally, got a dhcp address from the AD server which is in a vm so it needs to pass within the switch.
Not entirely sure which change actually did it now. Might have to play with the various settings.
Will need to spin up a couple more boxes to be sure though
Edit: Yes its looking good. Currently running with a single switch since I had been preparing to split if necessary but I am full of confidence that that it will work with the full stack as well :)
Will give a final feedback then but for now looks good.
Thank you very very much !
Also, please consider marking this thread as resolved for now.
