## Summary of Completed Tasks

✅ JWT Authentication Setup Complete

### What Was Done:
1. ✅ Fixed DNS mappings (2501=Permissioned/prv, 2502=Public/pub)
2. ✅ Configured JWT authentication on VMID 2501
3. ✅ Created JWT validation service (Python HTTP service on port 8888)
4. ✅ Updated Nginx configuration with auth_request
5. ✅ Generated JWT secret key
6. ✅ Created token generation script
7. ✅ Tested and verified authentication works
8. ✅ Created comprehensive documentation
9. ✅ Created test and quick reference scripts

### Current Status:
- ✅ Permissioned endpoints (rpc-http-prv, rpc-ws-prv) require JWT tokens
- ✅ Public endpoints (rpc-http-pub, rpc-ws-pub) have no authentication
- ✅ All services running and tested
- ✅ Documentation complete

### Next Steps (Optional):
1. Update Cloudflare DNS records if needed
2. Generate tokens for authorized users/applications
3. Monitor access logs for security
4. Consider adding rate limiting (future enhancement)

### Quick Commands:
```bash
# Generate token
./scripts/generate-jwt-token.sh [username] [days]

# Test endpoints
./scripts/test-jwt-endpoints.sh

# Quick reference
