Hi is it now possible to configure MX appliances in SSID VPN termination mode to act as a client DHCP server, this was not supported last time I looked.
not sure is this what you looking :
I'm also not sure if this is what you want:
When tunneling an SSID to an MX, you specify a local MX VLAN to terminate the SSID on. This VLAN is configured for DHCP and the client gets an IP out of that pool.
The MX can get its IP in any way: static, DHCP or PPPoE. But for a central device running as a concentrator I would only use an internet-connection with statically assigned IPs.
For the client-addressing: Running a DHCP-server is one of the base features of the MX. Probably that's the reason the above document does not mention it.
Ok, I think I really did not get your environment. Up to now I only ran the concentrator on devices in NAT-Mode. Although "officially" unsupported it works fine. You are right that in passthrough there is no DHCP-server. But you should be able to provide DHCP-services from the upstream device. Or is exactly this what you want to avoid?
Yes, here you are right that the MX still can not provide DHCP. Is there any reason you don't want to use the upstream device at your MX-location for this task? There has to be a L3 device like a router or a firewall and that device should provide DHCP or at least send the DHCP-requests as a relay to the corporate DHCP server.
In this use case I would look into the option to use the MX as the main firewall and use NAT-mode where you also can use DHCP-server.
