ACL on Cisco 3550 switch that will allow users access to the internal LAN, but not the internet
Posted on 2013-11-11
I have a VLAN configured on my Cisco 3550 switch like below. I need to create an ACL that allows users to access the LAN, but denies access to the internet and all outside resources. This VLAN needs to have complete unrestricted access to the LAN. I do have web based applications on this LAN, so they will still need to be able to use port 80 and port 443 locally. I just need to deny access to the internet. What would this ACL look like?
ip address 192.168.52.1 255.255.255.0
