trouble with dhcp new to pfsense and limited networking and freebsd knowledge please be gentle,

my problem seems to be no computers except the laptop (plugged into the lan interface) are not receiving ip addresses via dhcp thus theres no networking. since theres options for dhcp for internal ips on otpx I would assume it wouldn't be an issue? the lan received an internal ip of 192.168.1.1 which I would expect but the interface is connected to the laptop and id assume its the router that needs that ip address. assigning internal ip addresses to opt1 and 2 didn't seem to help either, (via cli or in the client) plus im not sure how that would work with wifi. when you say you need screenshots of the wan/lan config did you mean on the interface tab or the home screen ill assume the interface tab. for the most part things are left entirely default minus what I understand and what ive read im supposed to change. ! heres the rest of what you asked. thank you for the help.!

as said most everything has been left default

so under each interface tab and ipv4 configuration tab I have dhcp selected.
No. You are telling the system that every interface is a WAN and should OBTAIN its address using DHCP there.
- Set the LAN interfaces to Static IPv4
- Number them with (probably) unique RFC1918 /24s
- In Services > DHCP Server enable a DHCP Server for each LAN tab there.

its been over 10 years since my cisco classes that I struggled miserably in im assuming rfc1918/24s would be internal ip addresses with 255.255.255.0 subnets correct? thank you for the correction it makes sense.
-
Yes.
If you want to configure an IP network correctly you need to know things like IP subnets. Else you probably want to hire someone who does.

@derelict upon trying to assign a static ip of 192.168.1.100/24 to opt1 im getting an error that its overlapping with lan which has a static ip of 192.168.1.1/24 does each interface need a different range of ip addresses? I figured one computer could be 192.168.1.1 the next .2 the third .3 but apparently that's not possible. sorry I know this is pretty basic networking stuff but yeah this is why I struggled in the classes.

Interface 192.168.1.1/24 - DHCP pool 192.168.1.129 - 192.168.1.254
Interface 192.168.2.1/24 - DHCP pool 192.168.2.129 - 192.168.2.254
Interface 192.168.3.1/24 - DHCP pool 192.168.3.129 - 192.168.3.254 -

Yes, that's what differentiates one network from another. They cannot share IP space. If your LAN is configured to be 192.168.1.1/24, then any other interfaces cannot use 192.168.1.1 - 192.168.1.255. Derelict already showed how to divide up the DHCP ranges for each of your subnets.

@derelict thank you. Things I didn't understand in class before are making sense to me now suddenly. I appreciate everyone's patience.
