@scottalanmiller said in Dell N2048 Switch and IP ACL - I just killed part of my network...:
What's the reason for adding firewalling in the middle of your network? Hostile hosts?
To lock some down, more layers = good. We have for example database server on te1. If we can deny all, but then only allow access to that server for webserver, and wsus... if any machine is compromised or what not, its somewhat restricted.
