You're looking for features related to "Nebula Proxy Free". Nebula is an open-source, free, and global proxy server that allows users to access the internet securely and privately. Here are some features you might expect from Nebula Proxy Free:

Use a Free Tier Cloud Provider: Sign up for the Oracle Cloud "Always Free" tier or Google Cloud’s free trial to host your Lighthouse node.

• Nebula uses UDP by default; ensure NAT traversal or port forwarding for gateway/lighthouse.

2. Key components and concepts

• Nebula binary: the daemon that runs on each host.
• Certificate Authority (CA): generates node certificates (private CA used to sign node certs).
• Lighthouse: optional discovery/coordination service that helps peers find each other when behind NAT.
• Nebula network map: assigns virtual IPs (hostnames) and controls access via certificates and ACLs.
• ACLs (Access Control Lists): Nebula supports ACLs defining which Nebula virtual IPs/services can talk to each other.

💡 Pro Tip: If Nebula is blocked, try searching for "Ultraviolet" or "Interstellar," which use similar high-performance engines.
