Allow connections too localhost for uid0 then block to anything else

Can you please let me know the logic behind this? Basically, I want to
block any non-root user to access network.


sorry I misread.

The issue is that some services/daemons dont run as root but as normal system accounts and by blocking access too all non root users, you effectively block these services from working further alot of local services/daemons use too connect to and there isnt any benefit in blocking access to localhost.

my suggestion is too rather look at ensuring users are all in a certain group and then use iptables too block that group from accessing the network outside of localhost.

Thank you,
