I am doing some testing with a H320, vSZ-H version 126.96.36.199.510, AP firmware 188.8.131.52.771, specifically the DHCP/NAT on the AP feature.
I have it working fine over the WiFi, I have set up the DHCP pool attached to a VLAN (11), and then an SSID also on that VLAN, when I connect I get DHCP from the AP and connection NAT'd out to the internet. No issues.
However, if I configure the physical LAN ports on the H320 to be access ports on the same VLAN (11), I do not get DHCP from the AP, I get nothing.
I have configured the ports as access ports on another VLAN (200) that does exist on our local network and that passes through fine and I get DHCP from our DHCP server on VLAN 200, so VLAN passthrough seems to be working fine. VLAN 11 does not exist anywhere else on our network apart from the AP.
Is it possible to get DHCP from the AP to a device using the LAN ports?
DHCP/NAT Hierarchical Network Topology (HNT) Feature was released on Smartzone 5.0. Check the release note of 5.0 for the details. Prior to that version, it will only assign to WLAN devices. Hope that helps.
