Firewall only filters incoming traffic to instances, not outgoing traffic from them
No, Vultr Firewall does not filter outgoing traffic from instances. Vultr Firewall operates at the network edge to control incoming traffic to attached instances, providing centralized protection and consistent traffic filtering.
Outgoing traffic from an instance is managed by the instance itself, using software-based firewalls such as UFW, iptables, or firewalld. This design ensures that incoming traffic is strictly controlled at the network level while leaving full control of outbound connections to the instance.
