LayerStack provides a network-based and stateful firewall service for your cloud servers. Adding flexibility to firewall management across all of your cloud servers. This firewall supports filtering for both inbound and outbound traffic, allows you to configure specific rules as packet filter.
You can create firewall templates for pre-defined rule sets, which makes it easier to manage your cloud servers in bulk and apply firewall rules as soon as you create a new cloud server.
LayerStack Firewall dropped all packets by default. You can modify the rule sets in a Firewall Template to allow incoming or outgoing traffic access to the cloud servers from different ports within ICMP, TCP, and UDP protocols, also by targeting source or destination IP address.
You can narrow the scope of a firewall rule by specifying protocols and/or ports. You may find the specification on the below table:
|No protocol and port||ALL||If you select ALL, which means you do not specify a protocol, the firewall rule applies to all protocols and their applicable ports.|
|Protocol||TCP: ALL||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||TCP: 443||If you specify a protocol and a single port, only that port of the protocol is applied by the firewall rule.|
|Protocol and port range||TCP: 20-22||If you specify a protocol and port range, only the port range for the protocol is applied by the firewall rule.|
You can target specific IP address 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, which only accepts the IP address or a range of IP addresses you specified.
Firewall Management is available at no additional cost.
Firewall Management is available in every region.
