Switching from /24 to /23 LAN
-
Hopefully someone can answer this in 2 seconds. We have a running pfsense install with a /24 LAN. We are in need of more IPs for a growing company. We are trying to switch to a /23 on the LAN setup page.
All seems well when we look at the DHCP server, saying the pool could be as wide as 192.168.50.1 - 192.168.51.254 However, if I set any computer to 192.168.51.xxx with /23 subnet, I cannot ping the pfsense box.
What settings do I need to check?

Lan firewall rules correct?
-
Just standard set I believe. Attached.

Re-adjust
- Interface
- NAT
- DHCP-server
-> reboot, incl. all switches
Should do the trick

Re-writing this post…
Under your NAT you have 192.168.51.0/24 still hanging around under automatic.
Try using manual only and see if you can get rid of those entries...

Your automatic mappings have an overlap 192.168.50/23 overlaps with 192.168.51/24 why are both listed there? I would switch to manual completely and then switch back to automatic did that clear the issue.. You shouldn't be seeing both those networks in there.
