In the last post, VMware NSX™ Distributed Firewall installation and operation was verified. In this entry, the FTP (file transfer protocol) ALG (Application Level Gateway) is tested for associating data connections with originating control connections – something a stateless ACL (access control list) can’t do.
An added benefit over stateless ACLs – most compliance standards more easily recognize a stateful inspection-based firewall for access control requirements.
To check ALG support for a particular NSX version, refer to the VMware NSX Administration manual. VMware NSX version 6.2 supports FTP, CIFS, ORACLE TNS, MS-RPC, and SUN-RPC ALGs. Do expect additional ALG protocol support with future versions of NSX.
Assuming a default firewall rulebase for simplicity, and a basic setup:
Simplified diagram, along with connections for the following test:
Previously, an ESXi host command line was used to interact with the Distributed Firewall. Here, the NSX Manager Central CLI – a new option with NSX 6.2 – is used. Slightly different incantations, but the same results can be Continue reading

This week a couple of posts filtered through to my RSS feed that seem worth responding to on the certification front. Let’s begin with the second question first. This week, Ethan posted:

But how can you judge when that time has come? My thinking is based around this chart, taken from one Continue reading

A newbie exploring the mythical lands of SDN might decide to start at the ONF definition of SDN, which currently (November 2015) starts with a battle cry:
The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.
The rest of that same page is what I’d call the marketing definition of SDN: directly programmable, agile, centrally managed, programmatically configured, open standards based and vendor-neutral.
