LayerStack’s network-based and stateful firewall adds flexibility to firewall management across all of your cloud servers. Our firewall allows you to configure specific rules as a packet filter to screen both inbound and outbound traffic. You can use pre-defined rule sets to create firewall templates so you can manage your cloud servers in bulk and apply firewall rules as soon as you create a new cloud server.
LayerStack's firewall drops all packets by default. You can use a Firewall Template to modify the rule sets and allow specific traffic to go into and out of your cloud servers through different ports within the ICMP, TCP and UDP protocols. You can allow traffic from specific sources or destination IP addresses.
You can narrow the scope of a firewall rule by specifying protocols and/or ports. The specifications are as below:
|No protocol and port
|ALL means no protocol is specified. The firewall rule applies to all protocols and their applicable ports.
|If you specify a protocol without any port information, the firewall rule applies to that protocol and all of its applicable ports.
|Protocol and single port
|If you specify a protocol and a single port, the firewall rule only applies to that specific port of the protocol.
|Protocol and port range
|If you specify a protocol and a port range, the firewall rule only applies to the specified range of ports for the protocol.
You can target specific IP addresses or a range of IP addresses for inbound (ingress) and outbound (egress) rules.
Source IP Address: The source IP is only applicable to inbound (ingress) rules. You can specify an IP address or a range of IP addresses as sources for packets.
Destination IP Address: The destination IP is only applicable to outbound (egress) rules. Once set up, only traffic from the IP address or a range of IP addresses you specified is allowed to pass through.
Firewall is available in all regions.
