Good idea to configure sysctl.conf?

Hi,

I am in the process of setting up my VPS and I am currently looking at the sysctl.conf file.

Here are the changes I have made:

net.ipv4.conf.default.rp_filter=1

net.ipv4.conf.all.rp_filter=1

net.ipv4.tcp_syncookies=1

net.ipv4.ip_forward=0

net.ipv4.conf.all.accept_redirects = 0

net.ipv6.conf.all.accept_redirects = 0

net.ipv4.conf.all.send_redirects = 0

net.ipv4.conf.all.acceptsourceroute = 0

net.ipv6.conf.all.acceptsourceroute = 0

The Linode guides don't mention configuring this file and I was wondering if it was a good idea to make these changes and if not why?

Many thanks
