Avg Bid (USD)
Project Budget (USD)
$750 - $1500

Project Description:
would like to have iptables rules that will protect me from DDoS attacks that I have on my servesr. My servers are running Wowza Media Server. I have CDN with origin-edge structure where main origin server is constantly been attacked. Symptoms during attacks is that network traffic increase immediately to 1Gbps (our server's max) and server is stuck .
What I need specifically is as followed:
1.) Stop DDoS attacks on port 1935. That port is used for wowza streaming and should be open for other legitimates users.
2.) during attack I want DDoS to be stopped while other users to be able to stream to the server on port 1935.
3.) We prefer using iptables, but we are also open for other suggestions.
4.) Whole solution will be tested and paid once confirmed as valid (one-two weeks extensive testing).
5.) Only coders with previous experience (proved) of stopping DDoS attacks will be reviewed.

Please PM if you need any further information regarding the attack.
