Why can't I enable DHCP on a VLAN interface (I can enable DHCPv6 on it)?
-
I have a VLAN defined and assigned as interface OPT2. The OPT2 interface has a static IPv64 and IPv4 address configuration. I want to enable both DHCP and DHCPv6 on this interface but under Services>DHCP Server it only shows the LAN interface while under Services>DHCPv6 Server it shows LAN, OPT1 and OP2. Surely it is possible to enable regular DHCP on a VLAN interface? What am I missing?

@chrisjenk DHCP works fine on VLANs, I'm using many myself. I'd suggest going back and looking at the interface assignments and ipv4 config parameters.

What mask did you put on the network on the vlan - common mistake is defaults to like a /32 mask.. Which no you couldn't enable dhcp on that because there isn't any addresses to hand out.. That one comes up quite a bit actually.
