DDoS Prevention Guide

A DDoS is an overflow of information packets sent to an IP address (usually by malicious PC ninjas). Most common connections won't be able to handle all of the packets, and will then be effectively blocked from maintaining a connection until the attack lets up.

Chances are, if you are getting intermittent lag or get disconnected from a match randomly and then able to reconnect, you are most likely not being DDoS'd. DDoS attacks tend to start slow with minor latency issues and then gradually get worse to a point where you are unable to access any outside resources, not just League of Legends. For example, you will begin to disconnect and reconnect to Skype until eventually you will be unable to connect at all.


A DDoS can only work if the attacker has an IP address to target, so your primary goal is to protect your IP address. IP addresses are naturally hard to obtain, but some programs, such as Skype (which we will be using as an example), allow your IP address to be found by contacts. This amounts to virtually every compromised IP address in the LoL community. As it may take some time to change your IP address, it is recommended that you take steps to protect yourself well in advance of your matches.

Basic DDoS Protection

Step 1: Update Skype



Step 2: Proxy Skype Connection

Proxying your Skype is a fairly simple process, and is covered in this article:


There are many sources of free proxy servers available online. A few are referenced below and have options for many different countries. Find a server listed near you and test it out, and ensure that your Skype is functioning properly. This will mean the IP address shown to your Skype contacts is not your actual IP address. You must proxy Skype on every single device you use, including mobile phones or tablets.


Step 3: Changing your IP address




League of Legends Netlogs

To help diagnose a connection problem while playing LoL, you will likely be asked for your Network Logs (NetLogs). To find them, navigate to the client’s folder and go to Logs > Network Logs and locate files from the dates in which you suffered network issues. For example, my TRNA client is located in C:\Riot Games\NATR1, and I was lagging all day on 1/22/14. I would navigate to C:\Riot Games\NATR1\Logs\Network Logs, sort the files by “Date Modified,” and locate all files dated 1/22/14.

1) If you use Skype, update it and limit direct connections to your contact list as shown above.

2) If you add random people on Skype, you have 3 options to avoid a potential DDoS attack:

  • Only add contacts that you know and trust in real life.
  • Use a Skype proxy as shown above.
  • Do not use Skype.
