A client wants to add a fake hop when someone does a traceroute on his IP address. He has two ip addresses, and one interface (no problem, virtual interfaces solve it). How should I proceed? Is this even possible? I tried iptables forwarding but then it won't show up in a traceroute.
Sometimes there will be several IP addresses that spam my server, and it seems that most of them are coming from 1 source, but will slowly hit my server over time. Is there any way to block an IP coming from a traceroute?
For example, this morning I got some spam from this IP.
