Network Limits (Firewall)

Daytona provides network egress limiting for sandboxes to control internet access. This feature can be automatically applied based on your organization’s billing tier or manually configured for specific sandboxes.

Tier-Based Network Restrictions

Network limits are automatically applied to sandboxes based on your organization’s billing tier. This provides secure and controlled internet access for development environments:

  • Tier 1 & Tier 2: Network access is restricted and cannot be overridden at the sandbox level
  • Tier 3 & Tier 4: Full internet access is available by default, with the ability to configure custom network settings

To learn more about organization tiers and limits, see the Limits documentation.

Managing Network Access

Creating Sandboxes with Network Restrictions

You can control network access when creating sandboxes using the networkAllowList and networkBlockAll parameters:

from daytona import CreateSandboxFromSnapshotParams, Daytona


daytona = Daytona()


# Allow access to specific IP addresses (Wikipedia, X/Twitter, private network)
sandbox = daytona.create(CreateSandboxFromSnapshotParams(
    network_allow_list='208.80.154.232/32,199.16.156.103/32,192.168.1.0/24'
))


# Or block all network access
sandbox = daytona.create(CreateSandboxFromSnapshotParams(
    network_block_all=True
))

Network Allow List Format

The networkAllowList accepts up to 5 CIDR network blocks separated by commas:

  • Single IP: 208.80.154.232/32 (Wikipedia)
  • Subnet: 192.168.1.0/24 (Private network)
  • Multiple networks: 208.80.154.232/32,199.16.156.103/32,10.0.0.0/8

Organization Configuration

The network access policies for your organization are set automatically depending on your organization’s limits tier and cannot be modified by organization administrators. These policies determine the default network behavior for all sandboxes in your organization.

Testing Network Access

To test network connectivity from your sandbox:

Terminal window
# Test HTTP connectivity to allowed addresses
curl -I https://208.80.154.232


# Test package manager access (allowed on all tiers)
apt update  # For Ubuntu/Debian
npm ping    # For Node.js
pip install --dry-run requests  # For Python

Security Benefits

Network limits provide several security advantages:

  • Prevents data exfiltration from sandboxes
  • Reduces attack surface by limiting external connections
  • Complies with security policies for development environments
  • Enables fine-grained control over network access
