Why Ragnarok Online servers get attacked
Uptime is the whole game
Private RO servers are attacked hardest at launch and during War of Emperium, exactly when players are deciding where to settle. A downed login or map server on WoE night sends your guilds straight to a rival. Maelstrom sits in front of all three server ports so the flood never reaches your machine.
Anycast, near your players
Your Ragnarok Online 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 TCP. Your server's real IP stops being public, so it stops being a target.
Keep real player IPs
Turn on PROXY protocol and your Ragnarok Online server still logs each player's real IP for bans and analytics — no more seeing only the edge address.

FAQ
Ragnarok Online protection, answered
What ports does Ragnarok Online use, and do you cover them?
Ragnarok Online runs on TCP — login 6900, char 6121, map 5121 (rAthena/Hercules defaults — vary by server). All of it sits behind our anycast edge; you point the service at us and we forward clean traffic to your origin.
Will my Ragnarok Online 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 Ragnarok Online 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 Ragnarok Online server online
Protected in minutes. No hardware, no contract, from $5.00/month.
