Running speedtest.net Bans my own subnets ips, normal? #619

Closed rwrocket closed 7 years ago

rwrocket commented 7 years ago

Attached my config file I finally got pfring port mirror workinf with influxdb + grafana + mikrotik script.

All seems to work pretty well, now I am just fine tuning attack detection. For the sake of testing I have taken my attack thresholds right down so I can test what happens in an attack. I find that visiting speedtest.net consistently creates an attack and puts MY IP on the ban list.

My question is, is this normal? I expected maybe the external IPs outside my network would be banned and not my IP address that is inside the subnets in my networks_list.

Is this because when using speedtest.net the outside connections come from multiple IPs but the destination is just one IP on my side?

I wonder if there is a way to ban the DDoSers and not the DDoSed in an attack?

It's expected, FastNetMon does not block attackers, it blocks your IP. On Thu, 22 Dec 2016 at 03:46, rwrocket notifications@github.com wrote:

Btw, you could use flow spec mode and block attackers instead :) But it's pretty tricky sometimes and you could need to hack code for new attack patterns.

That is the idea of fastnetmon, it is going to block, or rather null route any address you (e.g. your ip addresses) control which has exceeded your defined thresholds.

Cheers, Mike

I got the same https://github.com/pavel-odintsov/fastnetmon/issues/606

I upped my thresholds and that solved it.

pavel-odintsov commented 7 years ago

So I'm closing ticket :)
