I'd like to configure an ACL for my wireless network with the IP range 192.168.240. However, my network's main gateway is at 192.168.30.250. My goal is to ensure that devices on the wireless network can only reach the internet and cannot connect to devices within my internal network.
Additionally, there are specific IP addresses I want to allow access from the wireless network. These include a firewall at 192.168.30.240, a device at 192.168.30.5, and my DNS server at 192.168.30.11
