Danilo, the problem is that there is a typo in the tutorial, you cannot enter spaces between the “=”. It should be like this: sysctl -w net.ipv4.conf.all.accept_redirects=0 I have an Ubuntu 16.04 Server which is acting as a router with multiple (VLAN) interfaces.

/proc/sys/net/ is one of this directories and directory contains subdirectories concerning various networking topics. Various configurations at the time of kernel compilation make different directories available here, such as appletalk, ethernet, ipv4, ipx, and ipv6. The neighbor cache in the Linux kernel isn't as simple as one would think. I'll try to explain some of the quirks with it.
