<![CDATA[No DHCP Server for newly added OPT interface]]>Hi forum.
I just bought and Netgate 1100 and are trying to set it up now,

I'll use the OPT interface for backup, so needing to add a extra subnet which is what the opt interface stands for.
But after activating the OPT interface - setting the IP - and press apply - and the apply the settings

I'm not getting the extra Subnet available as configuration under DHCP Server - and have now also been resetting the device - for thinking I've must be wrong in this - but no Subnet area are available on the DHCP Server - How can I fix this ?

I'm setting this up directly using the https access to the device, but yeah no subnet are able to be configured - khelp on what to do then ?
Also after an reboot there is still no subnet to be configured ? So what to do here ?
On all other Firewall of PFsense - I never experiencing this before ?

Try changing it to /24 or something bigger than /32.
