Simplified diagram, along with connections for the following test: two guest VMs running Centos: one running an FTP server, the other an FTP client.NSX installed, with the NSX Manager installed on the first host.three ESXi vSphere 6.0 hosts in a cluster.Do expect additional ALG protocol support with future versions of NSX.Īssuming a default firewall rulebase for simplicity, and a basic setup: VMware NSX version 6.2 supports FTP, CIFS, ORACLE TNS, MS-RPC, and SUN-RPC ALGs. To check ALG support for a particular NSX version, refer to the VMware NSX Administration manual. 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.Īn added benefit over stateless ACLs – most compliance standards more easily recognize a stateful inspection-based firewall for access control requirements. ![]() In the last post, VMware NSX™ Distributed Firewall installation and operation was verified.
