Alexander Eiblinger Posted July 28, 2021 Posted July 28, 2021 Hi, sorry, prop. a stupid question - but I was so far not figuring out the answer. I have a helios64 running - pretty standard installation, including openmediavault and docker, as described on the kobol help page. I realized that there are some firewall/iptables rules are set, as example: tester@helios64:/etc# sudo iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere state NEW,RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:8384 ACCEPT tcp -- anywhere anywhere tcp dpt:3128 ACCEPT tcp -- anywhere anywhere tcp dpt:1443 ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:microsoft-ds ACCEPT tcp -- anywhere anywhere tcp dpt:netbios-ssn ACCEPT udp -- anywhere anywhere udp dpt:netbios-dgm ACCEPT udp -- anywhere anywhere udp dpt:netbios-ns ACCEPT tcp -- anywhere anywhere tcp dpt:ftp ACCEPT tcp -- anywhere anywhere tcp dpt:49152 ACCEPT tcp -- anywhere anywhere tcp dpt:22000 ACCEPT udp -- anywhere anywhere udp dpt:1900 Chain FORWARD (policy ACCEPT) target prot opt source destination DOCKER-USER all -- anywhere anywhere DOCKER-ISOLATION-STAGE-1 all -- anywhere anywhere ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED DOCKER all -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT all -- anywhere anywhere ... What I was not able to figure out is, where these rules come from!? In openmediafault no firewall rules are set. I also was not able to find any iptables settings in /etc/network, etc. Anyone an idea where these rules are configured? And with which service they are setup? Thanks! 0 Quote

Heisath Posted July 28, 2021 Posted July 28, 2021 Armbian has no default iptables rules configured. So all rules are from either Docker or OpenMediaVault. 0 Quote
Alexander Eiblinger Posted July 29, 2021 Author Posted July 29, 2021 Thanks! Digged a little bi deeper in - the rules are actually mostly from openmediavault, did not realize that there were some set up before! Thanks to both on you for pointing me in the right direction! 0 Quote
