I am new to Linux and using Linux Daryna. I want to create a firewall on several boxes that limits the network access to two servers which both have static IP addresses.
The Linux box also needs access to the DHCP server for dynamic IP Do I do this by allowing all traffic on port 53?
I have figured out how to stop all traffic but can't get it down to the 2 IPs I want to access.
I Working on a gbox for a Library catalog box so it can only access the library servers and nothing else.
