Masscan in HTB VPN.

Hi guys!
I am trying to use masscan in HTB but i have a problem, it fail always, i can’t find any port open in any machine.

The command used is:

masscan -p 135

If i specify a interface using -e, masscan fail …

masscan -e utun1 -p 135

FAIL: failed to detect MAC address of interface: “utun1”
[hint] try something like “–adapter-mac 00-11-22-33-44-55”

But this interface doesn’t have any MAC.

This doesn’t happen scanning a external IP like
I am using MacOs, installed with ‘brew install masscan’

Any advice about that?
