Block connections above 50mbps

joodle

Is there any way to block connections wich uses more then 50mbps? (floods) Because my server keeps getting dossed wich 60-70mbps floods... and i already manually kept blocking those ip's for like the whole day now

Some more info: I'm running a cod4 server on it, so it gets alot of connections but those are 40-50kbps each, i don't want to block those

Hope someone can help me with this

Not at Server Level no.

Well, yes and no. Possibly if they do it for a few seconds or more with 50Mbit+ (as you cant block them if you don't know how fast it is before connection/flood for a few seconds)

there is. but most of this software isnt perfect and most of the time it doesnt work. Best just throttling instead.

@joodle,

Depending on who the provider is they might be able to set ACLs for you at Switch Level but I doubt they can block it on amount of bandwidth being used more protocol - TCP / UDP ect.

I assume high bandwidth = many packets per second. So the easiest way would be to rate-limit the amount of packages per second. That can be done with a simple iptables rule.

winston

can't you just do rate limiting in iptables?

agree with winston. I use this before but for other purpose. it just working.
