Why Killing Floor 2 servers get attacked
Uptime is the whole game
KF2 dedicated servers are small and easy targets without protection in front. We absorb the flood at the edge so your waves keep spawning.
Anycast, near your players
Your Killing Floor 2 address is announced from every Cloudflare location at once — Manila and Singapore for most of South East Asia — so traffic enters at the nearest edge.
Your real IP stays hidden
Players connect to the address we give you on UDP. Your server's real IP stops being public, so it stops being a target.
Keep real player IPs
Turn on PROXY protocol and your Killing Floor 2 server still logs each player's real IP for bans and analytics — no more seeing only the edge address.

FAQ
Killing Floor 2 protection, answered
What ports does Killing Floor 2 use, and do you cover them?
Killing Floor 2 runs on UDP — game 7777, query 27015. All of it sits behind our anycast edge; you point the service at us and we forward clean traffic to your origin.
Will my Killing Floor 2 server still see players' real IPs?
Yes, if you turn on PROXY protocol at checkout and read it on your side. v1 works with TCP, Simple with UDP, v2 with both. Without it your server sees our edge address instead.
How fast can I get my Killing Floor 2 server protected?
Minutes. Pay by card, give us your backend IP and port, and we hand you a public address to give your players. Mitigation is always-on from that moment.
Keep your Killing Floor 2 server online
Protected in minutes. No hardware, no contract, from $5.00/month.
