# PUT /sandboxes/{sandboxID}/network

`PUT /sandboxes/{sandboxID}/network`

Update the network configuration for a running sandbox. Replaces the current egress rules with the provided configuration. Omitting field clears it.

## Path parameters

- `sandboxID` string, required

## Request body

- SandboxNetworkUpdateConfig — Network configuration update for a running sandbox. Replaces the current egress rules with the provided configuration. Omitting a field clears it.
  - `allowOut` string[] — List of allowed destinations for egress traffic. Each entry can be a CIDR block (e.g. "8.8.8.8/32"), a bare IP address (e.g. "8.8.8.8"), or a domain name (e.g. "example.com", "*.example.com"). Allowed entries always take precedence over denied entries.
  - `denyOut` string[] — List of denied CIDR blocks or IP addresses for egress traffic. Domain names are not supported for deny rules.
  - `rules` object — Per-domain transform rules. Replaces all existing rules when provided.
  - `allow_internet_access` boolean — Allow sandbox to access the internet. When set to false, it behaves the same as specifying denyOut to 0.0.0.0/0 in the network config.
