    <description>&lt;P&gt;This sounds like a network configuration problem. If it can't talk across hosts, i would probably start by looking at your VLAN configuration. Not in VMware, but at the switch level for all 3 hosts. Get a copy of the switchport configuration for ALL ESXi hosts from your network team and document it. Look for any differences.&lt;/P&gt;&lt;P&gt;Is the port type set to Trunk or Access? If it is configured as a Trunk port, the switch config needs to tag VLAN 20 to the hosts interface(s) in order to pass traffic for that VLAN.&lt;/P&gt;&lt;P&gt;You can get some visibility of possible mis-configuration via your Distributed switch Healthcheck tool. To enable this, Select your vDS and go to Configure → Healthcheck → Edit, then set the &lt;STRONG&gt;VLAN and MTU&lt;/STRONG&gt; state to &lt;STRONG&gt;Enabled.&amp;nbsp;&lt;/STRONG&gt;This will monitor your host configuration and alert you to any mismatch with the switch config, particularly for VLANs.&lt;/P&gt;&lt;P&gt;Also check Subnet masks and Gateways are 100% correct.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;I create cluster (HA enable, DRS enable, vSAN enable, create Distributed Switch) with 3 host (ProLiant BL460c Gen9) all work fine.&lt;/P&gt;&lt;P&gt;I have vm Mikrotik on cluster and have 2 network interface(WAN and LAN) i create on&amp;nbsp;Distributed Switch new port group DLAN and set VLAN type - VLAN&lt;BR /&gt;VLAN ID - 20&lt;BR /&gt;and asignet to interface Mikrotik LAN.&lt;BR /&gt;If Mikrotik and other virtual mashine findingi on same host, but if on differents host not work.&lt;/P&gt;&lt;P&gt;Is there a way to configure it to work even when the machines are on different hosts?&lt;BR /&gt;&lt;BR /&gt;Example:&lt;BR /&gt;Host1&lt;BR /&gt;&amp;nbsp;- Mikrotik - WAN&amp;nbsp;connect to port group VM Network, LAN&amp;nbsp;connect to port group DLAN and run DHCP&lt;BR /&gt;&amp;nbsp;- VM1 - connect to port group DLAN and have ip address from Mikrotik DHCP&lt;BR /&gt;Host2&lt;BR /&gt;&amp;nbsp;- VM2 -&amp;nbsp;connect to port group DLAN and not work network&lt;BR /&gt;Host3&lt;BR /&gt;&amp;nbsp;- VM3 -&amp;nbsp;connect to port group DLAN and not work network&lt;BR /&gt;&lt;BR /&gt;Thanks!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
