Nessus Scan...Unraid IP Forwarding Necessary?

Recommended Posts

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... "echo 0 > /proc/sys/net/ipv4/ip_forward"

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.
