Unable to enable DHCP server for OPT1 interface

phil.davis

When an interface has StaticIPv4 and a static IPv4 address and CIDR then there should be a tab for that interface in DHCP Server.

Is the IPv4 type of the interface set to Static IPv4?

What other odd settings did you make? (e.g. it should NOT have an upstream gateway specified)

Thank's for the reply! :)

Well, I have configured it with an IPv4 address and no other settings modified.
To me it's just the same as LAN except for the IP address, but I suppose something is off anyhow.. :P

Is "not the same" ;) you have a /32 (LAN have /24 )

mindless

Omg!!
I knew it was something really small and stupid I!! :-[ ;D
Think I have looked at that page like a 100 times and "It looks just like my LAN"..

Now my DHCP server works just fine!

Anyhow, thank you sooo much for noticing my stupid error! :)

Sorry for the resurrection, but I have set my interfaces to have Static IPv4 addresses and the option in Services > DHCPv6 Server & RA doesn't show up.

Help please?

Here's a screenshot of what I'm looking at after clicking "Services > DHCPv6 Server & RA" and it won't give me the option to select another interface. I know for a fact that my OPT interfaces have DHCPv6 as the address method, but I also can't select another interface, other than LAN, to Track Interface with WAN.

(Sorry, apparently I can't edit a post after 3600 seconds)

You can even disable / remove the IPv4 address on your interface.
For "DHCPv6 Server & RA" to work, you should have a valid IPv6 set up.
If your question was remotely related to the subject of this thread, you have set a /128. Which leave zero space for a pool, so DHCP (V6) isn't possible.
You didn't do that ?? Did you ?
