LAN2 Cannot Connect to main LAN

IanHK

Current status:

I removed the "duplicate" static mappings so now LAN only has static IPs defined for the wired devices, and LAN2 only has static mappings for the WiFi devices.
For my workstation, I removed all static mappings so it is just picku\ing up DHCP settings.
LAN2 is defined as 192.168.2.0/25 - I only did this to force a change to be saved to see if it would solve the 255.0.0.0 issue
I rebooted pfSense
I double-checked the workstation is using DCHP - when the pfSense box / AP went wonky last night I had a fixed IP which may have caused the situation earlier today, not sure of anything anymore!

Now, with workstation connected directly to LAN2, I am seeing an x.x.2.x DHCP assigned IP - as expected - but the subnet mask is STILL 255.0.0.0

Attached items as requested:

ipconfig /all
arp -a

hmmm your getting DHCP from the pfSense LAN2 interface, thats why I asked for the arp -a, to tie in the DHCP server IP and the MAC address.

The subnet mask is now /25 rather than /24.

Can you post a screenshot from the LAN2 config and the DHCP settings for LAN2.

Thanks - here you go...

Remove DHCP option 1 and try again.

No need to go anywhere near the options config for standard users.

You've got to be kidding! That just looked like a default panel with nothing saved - pfSense usually adds rows of saved items in a table underneath.

Anyway, I needed to add another row to get a delete option but when i did, the DHCP assigned mask is immediately the expected 255.255.255.0 and from my x.x.2.x workstation I can access the NAS webgui on x.x.1.x

So grateful - many, many thanks.

You can just blank the entry :)

You should be getting a mask of 255.255.255.128 if you have a /25 mask set.

IanHK

Yes, that's what I get with the /25 setting. Thanks again.
