Firewall
The Firewall tab on a VM lets you attach or detach a firewall policy to control what inbound traffic is allowed.
Attach a policy
- Open the VM detail page → Firewall tab
- Select a policy from the Attach policy dropdown
- Click Attach
The policy's allow rules are enforced immediately. If no policy is attached, the message "No firewall policies are attached to this VM" is shown.
warning
Attaching a policy activates default inbound deny — only traffic matching allow rules gets through. Confirm port 22 is included in the policy before attaching or you will lose rumpty ssh access.
Detach a policy
Click Detach next to the active policy. Traffic reverts to the workspace default behaviour.
Manage policies
Click View policies to go to the Firewall Policies section where you can create policies and manage rules.
For full details see Firewall Policies.
