Unified Rule Management
Unlike other providers, Cosmicguard manages TCP, UDP, and ICMP in a single unified list. This allows you to see your entire security posture at a glance.
- Protocol Agnostic: Create rules for specific ports regardless of protocol.
- Port Ranges: Support for single ports (e.g.,
25565) or wide ranges (e.g., 10000-20000).
Advanced Filter Types
Cosmicguard offers high-level “Logic Blocks” for custom rules:
| Filter Name | Description |
|---|
| Any TCP Application | General TCP hardening. |
| SynCookies | Advanced SYN-flood protection for high-traffic environments. |
| Steam Query | Hardened validation for Valve’s query protocol. |
| FiveM L7 | Deep packet inspection for FiveM servers. |
| Cloudflare Only | Whitelist traffic coming only from Cloudflare nodes (Web hosting). |
| RakNet v2 | Latest validation for modern survival games. |
Rule Configuration
- Log in to the Firewall Panel.
- Click the IP Addresses tab and select your Cosmicguard IP.
- Click Filtering Rules and then Create New Rule.
- Protocol: Specify TCP, UDP, or ICMP.
- Port Range: The specific port(s) to protect.
- Logic: Choose from the specialized engines.
- Action: Set to Allow or Deny.
Rule Ordering
In Cosmicguard, rules are checked top-to-bottom. If you have a general “Deny All UDP” rule, ensure your game’s “Allow” rules are placed above it.
