x86 and ethernet/port isolation

I setup a small lab router on esxi with 2 ethernet ports.

Ether1 - ip of 10.10.0.1/24
Ether2 - no ip address given, but attached to a busy network off the host machine

I created a bridge with only Ether2 attached

If I run torch on Ether1, I am seeing traffic from Ether2?

Is there not a way to isolate ethernet ports on x86?

uhm… this is odd/spooky… I removed the bridge, recreated it, built it the same exact way, and now I’m no longer seeing traffic from ether2 with torch on ether1…

maybe u should run the torch on ether1 when ether2 network is busy

generated quite a bit of traffic across the network that ether2 is attached to, and still nothing showing on ether1. still weird, but, at least it’s doing what I want right now.
