I blocked an IP with this command first:
route add -host x.x.x.x reject
I still see the traffic in
iftop. I tried adding this rule in iptables:
-I INPUT -s x.x.x.x -j DROP
Still, when running
iftop it shows up at the top. Is there a way to block it completely?
Note that this is a VPS and I'm unable to configure any firewalls.
