DHCP Blue Interface missing

Networking
1

With my current config I am missing the DHCP options for the BLUE interface. I did not attach the device to an interface because I wish to use a separate VLAN on the green interface.

As you can see above there is no BLUE interface to configure.

How would I go about adding/enabling these options?

Current /var/ipfire/dhcp/dhcp.conf

deny bootp;     #default
authoritative;
ddns-update-style none;

subnet 192.168.1.0 netmask 255.255.255.0 #GREEN
{
pool {
        range 192.168.1.100 192.168.1.249;
     }
        option subnet-mask 255.255.255.0;
        option domain-name "local";
        option routers 192.168.1.1;
        option domain-name-servers 192.168.1.2;
        option ntp-servers 192.168.1.1;
        default-lease-time 3600;
        max-lease-time 7200;
} #GREEN

include "/var/ipfire/dhcp/dhcpd.conf.local";

Should it look like…

deny bootp;     #default
authoritative;
ddns-update-style none;

subnet 192.168.1.0 netmask 255.255.255.0 #GREEN
{
pool {
        range 192.168.1.100 192.168.1.249;
     }
        option subnet-mask 255.255.255.0;
        option domain-name "local";
        option routers 192.168.1.1;
        option domain-name-servers 192.168.1.2;
        option ntp-servers 192.168.1.1;
        default-lease-time 3600;
        max-lease-time 7200;
} #GREEN

subnet 192.168.2.0 netmask 255.255.255.0 #BLUE
{
pool {
        range 192.168.2.100 192.168.2.249;
     }
        option subnet-mask 255.255.255.0;
        option domain-name "local";
        option routers 192.168.2.1;
        option domain-name-servers 192.168.1.2;
        option ntp-servers 192.168.1.1;
        default-lease-time 3600;
        max-lease-time 7200;
} #BLUE

Any help would be appreciated!

Perhaps start here.

You will have to run setup to add blue network first.

Thank you for the info, I gone over that page extensively trying to see if I missed something. Either I simply cannot see it, Or…

Everything related to the BLUE interface is there except the DHCP options.

When you run setup add blue zone.
So red,green blue
No nic assignment for blue.
Then it should show up in WUI.
I sometimes think it would be easier if
WUI had a 4 network buy default.
Then you could add them later, more easily.

Yes, I did exactly that. The interface shows up.

Its just the DHCP options that do not show up.

Sould be in WUI.
Can run setup and set ip and dhcp for each zone.

It only asked me for the info on the GREEN interface. I setup another router in a VM to test with and it did not ask my DHCP info for the BLUE either.

DHCP should look like this.

Have no vlans
In setup can you link same nic to both zones?

Right! For some reason the Blue Interface is no showing up for me in the DHCP section.

I even have these options…

But there are not DHCP clients because I cant seem to config the DHCP section.

Does the blue zone need to be in bridge mode.

OMG, I found it! Thank you. You did lead me to it. It WAS in the setup. I had to add an “Uknown” interface to BLUE that had the corresponding MAC in the list of interfaces in “ip address”. Once I completed it, The options for BLUE in the UI came up.

Thank you so much!
