Hello, I'm an admin of Lost World project (www.l2lwg.com) and my server was attacked heavily by Stalone (l2tales, l2vadc) it was going down, a lot of dc and shit like that. Finally, I've found a solution, which costs:
150 Euro / month
50 Euro / 10 days
I forgot to mention, that you can get 24 hours free trial, and free configuration on your LINUX.
Now mostly I'm under attack with 120gbps - 170gbps UDP flood :ooo
But server works perfectly, no delays, no disconnects.
Provider gives 2 IP's, one for login, one for gameserver.
It's a tunnel protection, so all players gonna have different IP's :)
If you are interested in this kind of protection, contact to skype: L2LWG.com
I'm not selling this protection, I'll just give you a person, who does that, and I will get a discount.
