      Hello all.
      Fairly new to VLANs and having some troubles.
      I have setup multiple VLANS and I can't get them to talk right.
      VLAN 3 is setup on the 10.0.3.x Subent.
      I have rules setup on LAN to allow all from VLAN and another the other way.
      I have a rule on VLAN to allow * to * for any.

      But I can't get 3 to talk to LAN and would appreciate any input:

      C:\Users\tiny>ipconfig

        Not a good test with Windows. They block ICMP out of their own subnet.

          what are you pinging.. Is it running a firewall.. For example out of the box windows does not allow pings from other networks other than its own local segment.  Adjust the firewall running on specific hosts in different vlans to allow traffic you want from your other vlans.

            Not enough info for us to even attempt assistance at this point.  Post a network map, so we know how things are connected and configured.

              Ok, I have made some serious progress here!

              My Vlans are now talking fine and happy. :)
              My only remaining issue is a DHCP issue.
              I have a SmartThings Hub which is not playing nice.
              It's now plugged into the same port that the PC was initially was in, meaning it would get flagged as VLAN3 with an IP range in 10.0.3.x.
              The only remaining issue is DHCP refuses to work for the device.
              It works for the PC (Tiny) , but not the hub:
