I had a look at the
iptables rules from Tails OS
Briefly speaking, what is the purpose of the
lan iptables rules?
Chain lan (3 references) target prot opt source destination REJECT tcp -- anywhere anywhere tcp dpt:domain reject-with icmp-port-unreachable REJECT udp -- anywhere anywhere udp dpt:domain reject-with icmp-port-unreachable REJECT all -- anywhere anywhere owner UID match postgres reject-with icmp-port-unreachable ACCEPT all -- anywhere anywhere
