# Detach a VPC from a firewall

<!-- cspell:ignore FortiGate -->

Detaching a VPC takes the firewall out of that network. The VPC itself stays, with everything else
in it. A firewall always keeps at least one VPC: you can detach any VPC, including the one you
picked when you created it, while the firewall has two or more.

## Before you begin

- The firewall has at least two VPCs. To move a firewall to a new VPC, attach the new one first.
  See [Attach a VPC to a firewall](/myaccount/firewall/how-to/attach-a-vpc-to-a-firewall/).
- The firewall is **Running** or **Powered off**, and unlocked.
- Your role has both the update and the create Firewall permissions. Update shows **+**, **Attach
  VPC**, and the cancel icon, and create lets MyAccount make the change. If a control is missing
  or the change fails, ask your account's administrator to add both to your role.
- You have moved any traffic you still need off that VPC's path through the firewall. Traffic
  between that VPC and the firewall stops once you detach it.

## Detach the VPC

1. In MyAccount, under **Network**, click **Firewall**.
2. On **Manage Firewall**, click the firewall, then its **Network** tab.
3. Under **Associated VPC name**, click the cancel icon next to the VPC's name.
4. In **Detach VPC**, which asks **Are you sure you want to detach VPC: <name>**, click
   **Detach VPC**.

**VPC detach operation successfully done** confirms it.

If one of these shows instead, the VPC stays attached:

- **At least one VPC is required on a firewall. Please attach a new VPC before removing this one.**:
  attach another VPC first.
- **VPC cannot be attach/detach in Locked State.**: choose **Unlock Firewall** first.
- **This action can be perform only on RUNNING/ POWEROFF**: wait until the firewall is **Running**
  or **Powered off**.
- **The node is currently updating its VPC information. Please try again in a few moments.**: try
  again in a few minutes.

For help with any message, see
[I cannot attach or detach a VPC](/myaccount/firewall/troubleshooting/firewall/#i-cannot-attach-or-detach-a-vpc).

## Check the VPC is detached

On the firewall's **Network** tab, the VPC is gone from **Associated VPC name**.

Next, remove the policies and routes for that network on the FortiGate's screen. See
[Sign in to the FortiGate](/myaccount/firewall/how-to/sign-in-to-the-fortigate/).
