How do you stop a botnet DDOS?

[KIA]

Proper DDoS protection is extremely expensive. What's your budget?
How much incoming traffic?
How many packets per second?

Get their details posted. He won't do it for long haha. A few friends and I have a good solution and it works well, we haven't been attacked for months now

Give them a parking ticket ?

Please describe these mythical devices - all the ISPs will be amazed these exist.

Well everyone has different solutions. But firewalls can do things like rate limiting the interface and look for Resource starvation attacks (i.e. the use of SYN/FYN waits).

You will also be pleased to know many ISP's also offer DDOS mitigation if your a big enough customer! BT certainly offer it.

Yeah I don't think DDOS mitigation will be particularly easy, the DDOSes that have occured hit with 8-12GB of data each second from international sources. Wellp. Unless someone has a miracle, I think I'll just leave it be.
