Hello, Tyler L.
Thank you for reaching out!
The security rules within TDNSG1 are actively filtering inbound traffic for TD2 because all of its rules explicitly target the destination subnet 10.0.2.0/24 (where TD2 is connected).
As mentioned in the explanation, the issue is not caused by TDNSG1 blocking traffic, but rather that TD2 is not listening on port 443. Even though the NSG allows the connection, if no service is actively listening on port 443, the connection attempt will fail.
I hope this helps! Let us know if you need further assistance.
Regards,
JR @ Tutorials Dojo
