Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere LOG all -- loopback/8 anywhere LOG level warning DROP all -- loopback/8 anywhere LOG all -- anywhere anywhere LOG level warning DROP all -- anywhere anywhere Chain FORWARD (policy DROP) target prot opt source destination LOG all -- anywhere anywhere LOG level warning DROP all -- anywhere anywhere Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere LOG all -- anywhere anywhere LOG level warning DROP all -- anywhere anywhere I tried 'iptables -F' before bringing up the connection, without success pinging.
