You could put up a firewall.
Outpost is pretty good.

 

[ntmr]

Block tcp traffic on ports 67, 135 and 1025.
Block udp traffic on ports 67, 135, 137, 138 and 445.
Block icmp packets of types 0, 3, 14, 16, 8, 13 and 15.

Somethings will not work with these rules (shared printers and directories for example).

It can't block an UDP SYN Flood, but will help on the small attacks.

Let your router block all connections ( you can't host an ot anymore then) but you don't have the problem either!

He could host it on a private network then, the router would only block all incoming connections but not private connection.

@Topic,

There is no real way to block DDoS attacks. There is equipment that you can purchase, but that won't prevent all of them. Most of the equipment is very high in cost too ($2k-35k) and meant for an actual computer host service.

There are also minor settings that you can change, like Nightmare has already suggested, but like he said it will only reducing minor ones. A good firewall will prevent your computer from locking up but it will still cause your internet to be reduced to a crawl.

Would be bad blocking of port 67 if hes getting and IP via dhcp from his ISP. Result: No ip at all!

I said: somethings will not work with the rules
Btw...
Port 67 is used by Bootstrap Protocol Server, then it can cause problems only if you run a dhcp server on your computer.

So what should I do to save it from "small" attacks? I'm using a Virtual Server to run my OTS. My Ot's also got a Homepage..

What the DDoS attacks are doing?
Lag?
Server crash?
Database crash?

I know what is a DDoS

I just want to know what the attack is causing.

The attacker may be using a security flaw in the website to put down the database or just flooding to connection to cause lag.
