bsim Posted December 12, 2018 Share Posted December 12, 2018 (edited) So, I've been learning about unraids network attack surface, and running Nessus against my server shows a few Medium vulnerabilities... IP Forwarding from my experience, unless the system is a router/firewall should be disabled...Should I disable it? ------------------------------------------------------------------------------------ IP Forwarding Enabled To disable in linux...

ken-ji Posted December 12, 2018 Share Posted December 12, 2018 If you disable with IP forwarding, you'll break the stock docker networking. Stock docker networking creates an internal bridge docker0 where all the containers are connected to. IP forwarding is then used to route the containers outbound connections. Port mapping uses port forwarding to exposes any necessary (declared) services. 1 Quote Link to comment
bsim Posted December 13, 2018 Author Share Posted December 13, 2018 Does it have a possibility of being abused in a network? Quote Link to comment
ken-ji Posted December 13, 2018 Share Posted December 13, 2018 To stretch the imagination, maybe, but I can't imagine a way it can be abused. Quote Link to comment
