OCI Firewall

...

Information

Access to an OCI cloud instance can be controlled by

• an external firewall,
• the operating system firewall of the instance (see Installing the VE License Server and Charon -SSP Packages in the CloudEmulator),
• security list of the subnet to which the instance belongs, and
• VNIC-specific Network Security Groups.

The In addition to allowing SSH, the different firewall levels must be configured to permit at least TCP port 8083 to enable a license client to access a the ports required by the VE license server. If the web interface is to be used, TCP port 8084 must also be allowed.

Security Lists

Security lists form the original type of virtual firewall offered by the Oracle cloud network service.

...

Please see the relevant Oracle documentation for more information and configuration detail.

Please note: Traffic is allowed if any rule in any of the relevant lists and groups allows the traffic. Traffic is also allowed if it  is the response traffic of a permitted tracked connection. In addition to allowing SSH access, at least TCP port 8083 must be allowed to enable a license client to access a VE license server. If the web interface is to be used, TCP port 8084 must also be allowed.

AWS Firewall

In addition to allowing SSH access, the different firewall levels must be configured to permit at least TCP port 8083 to enable a license client to access a VE license server. If the web interface is to be used, TCP port 8084 must also be allowedthe ports required by the VE license server.

Network ACLs

A network ACL applies to a subnet as a whole. Only one network ACL per subnet is allowed. The rules in a network ACL are stateless (i.e., return traffic must be explicitly allowed). Rules are evaluated starting from the lowest rule number. After the first match the search is terminated.

In addition to allowing SSH access, the different firewall levels must be configured to permit at least TCP port 8083 to enable a license client to access a VE license server. If the web interface is to be used, TCP port 8084 must also be allowedthe ports required by the VE license server.

Network Security Groups

Network Security Groups can be associated to interfaces or subnets. Security rules in network security groups enable you to filter the type of network traffic that can flow in and out of virtual network subnets and network interfaces. When a cloud instance is created, you can assign a default security group to its interface (allowing SSH). Please refer to the following tutorial for more information: https://docs.microsoft.com/en-us/azure/virtual-network/tutorial-filter-network-traffic.

Google Cloud Firewall Rules

...

• Each rule is either for incoming or outgoing traffic. It can allow or deny traffic.
• Only IPv4 traffic is supported.
• Firewall rules are stateful (return traffic for an established connection is allowed).
• If TCP traffic is fragmented, a rule is only applied to the first fragment of a packet.

IBM Firewall Information

Access to an IBM cloud instance can be controlled by 

• an external firewall,
• the operating system firewall of the instance,
• IBM-specific security groups, and
• IBM-specific subnet ACLs.

In addition to allowing SSH, the different firewall levels must be configured to permit the ports required by the VE license server.

IBM Cloud Security Groups

Security Groups are associated with a virtual server instance. They have the following characteristics:

• Stateful: once an inbound connection is permitted, return traffic is allowed.
• Only allow rules are possible.
• All rules are considered to determine if traffic should be permitted.
• An instance can have several security groups.

IBM Cloud Subnet ACLs

Subnet ACLs are associated with subnets in a VPC. They have the following characteristics:

• Stateless: inbound and outbound connections must be explicitly allowed.
• Allow and deny rules are possible.
• Rules are processed in sequence.
• One ACL can be assigned to several subnets.
• The default ACL allows all traffic.
