Use the main router for DHCP. Same page again, now the DHCP Server tab. Should be at the General Setup sub-tab. (In version 18.06 and earlier of LuCI, no tabs: just scroll down.) Ensure the Ignore interface checkbox is checked.
Use the main router for DHCP doesnt exist, or I am inept and can't find the option..
Once I disabe the DHCP server, I can only connect to the router if I manually set my IP within it's range on my PC (windows and rebooted in linux too). I can't get an IP from it. Is there a DHCP Relay option or something I need to enable??
setting my main router as DHCP server seems to not be an option as far as I can see in the GUI.
I'm stuck.
I know that the newer version of OpenWRT use DSA, so perhaps the wiki is out of date?
IDK what I'm doing wrong besides not being able to set my main OPNsense router as the DHCP server (it serves 3 separate networks DHCP no problem)
Thanks!
The document is just poorly worded. What they mean is it tells you how to use the main router for DHCP, not that you need to find an option called "Use main router for DHCP" (Someone should go over the documentation and rewrite most of it, to be quite frank)
Is your main router connected to the LAN-ports or the WAN-port?
The default configuration of a main router is that it is the LAN network's DHCP server. So you don't have to re-configure anything there.
Turning off the DHCP server in the dumb APs is important so you don't have multiple conflicting DHCP servers on the network.
Of course with the DHCP server turned off, the router is difficult to operate stand-alone. It needs to be connected to the larger network that includes a DHCP server. Do not apply any changes until you get to step 14, then after the changes are applied, you can connect the dumb AP to your house network.
