![]() ![]() P ull the filters on all vNICs for that host, while also verifying the Distributed Firewall is active with ‘show dfw host host-32 summarize-dvfilter’.Įxtracting the filter name from the results, we notice ‘nic-71375-eth0-vmware-sfw.2’. The cluster name is required to determine hosts in the domain.Ībove, host-32 runs the FTP server VM. In the screenshot below, ‘ ssh ’ ‘ show cluster all ’ then ‘ show cluster domain-c26 ’ are executed. ![]() Determine the cluster and VM names with ‘show cluster all’ and ‘show cluster ’. Once in, access to ‘show’ commands is available. Slightly different incantations, but the same results can be had with either CLI.įirst, log into the NSX Manager via SSH. ![]() Here, the NSX Manager Central CLI – a new option with NSX 6.2 – is used. Previously, an ESXi host command line was used to interact with the Distributed Firewall. 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. ![]()
