VPC Firewall
The VPC firewall controls inbound traffic to your VPC at the gateway level. Rules are defined separately for IPv4 and IPv6 traffic.
Navigate to Firewall within your VPC to manage firewall rules.
Note: VPC firewall rules are distinct from the VM Interface Firewall, which provides API-managed ACLs on individual VM network interfaces. The VPC firewall operates at the gateway and applies to all traffic entering the VPC.
IPv4 Rules
The IPv4 Rules tab shows all inbound IPv4 firewall rules applied to the VPC gateway.
Adding a Rule
- Click + Add under Inbound IPv4 Rules.
- Select the Protocol — All, ICMP, TCP, or UDP.
- Enter a Port or port range (for TCP/UDP).
- Enter the Source — an IP address or CIDR range to allow or deny.
- Click Add to save the rule.
IPv6 Rules
The IPv6 Rules tab works identically to IPv4. Click + Add to create inbound IPv6 rules with the same protocol, port, and source options.
Syncing Rules
After adding, editing, or deleting firewall rules, you must click Sync Rules to apply the changes to the gateway. The Sync Rules button is only available when there are pending changes that have not yet been applied.
Note: Firewall rules are not active until you sync them. Always click Sync Rules after making changes to ensure the gateway configuration is up to date.
Next Steps
- NAT Rules — configure inbound and outbound NAT
- Gateway — bastion, floating IPs, and IP reservations
- Load Balancing — distribute traffic across backend VMs
