I decided to write this blog post because I received multiple customer requests asking for differences between NSGs and SLs, where and when to use one or another or both and the best practices. NSGs stands for Network Security Groups, a security mechanism that we have added to OCI few time back. NSGs can be more granular in terms of security and can be used with or without Security Lists, You can follow the link from OCI public documentation to find more about NSGs vs...

Introduction There are some cases when our customers are reporting that the TCP connections from On-premise to OCI just hangs apparently without any good reason. In the next discussion we will introduce an important detail that usually is not taken into consideration when the connection hanging troubleshooting is made. The case discussed is when the TCP three way handshake completes successfully but when starting sending the data the connection is hanging. Why? In modern TCP...

Deploying Virtual Firewalls (vFW) in OCI

In the previous article I created a Palo Alto VM in OCI and now i will continue with a classic use-case: hide a server behind the firewall (static-NAT) What is different in the cloud from on-premise? Well, on-premise the firewall would have on it's external (outside) interface a public IP address and when you do a NAT the packet that will exit the firewall will have a public IP address. In the cloud, the public IP address is ephemeral and it is not configured on the vNIC....

Introduction By having multiple connections to OCI services, you may have a few questions during the routing configuration on the On-Premise router/firewall to avoid the asymmetric routing. The scope of this blog is to explain how the On-Premise CPEs needs to be configured in order to access Oracle Services Network for short OSN when we have multiple paths: FastConnect Private and Public Peering and Internet. We will also explain how to avoid the asymmetric routing that can...

Network Appliances are getting very popular in the cloud implementations. Customers are using Virtual and Physical Network appliances in their on-premise implementations and with time they are very familiar with the look and feel of the GUI and they want the same familiar look in the cloud. Beside this, the cloud Network security doesn't provide the level of control that might be required if, for example, the customer is in financial business. They are constrained by the...
