Help changing subnet
«

Good morning,
I am still a novice with Opnsense but have managed to get my home network setup and working great with my unRaid server.
One issue however is remote access via Wireguard (using the built-in unRaid Wireguard feature). Searching online it would appear that my issue is caused by an overlapping IP range. As such I need to change my home subnet from 192.168.1.0/24 to something more unique, ie 192.168.55.0/24
I made a stupid error yesterday by changing my LAN subnet, then I could no longer access anything as pretty much everything I have in the house has a static IP (which was still held in the old subnet range. Anyways, after a restore I am back to try again.
So far for my second attempt I have;
*Removed all static IP allocations.
*Reduced DHCP lease time to 1,800 seconds.
*Increased subnet DHCP range to; 192.168.1.2-192.168.1.254
My question is, what should be my next step? If I change my LAN IPv4 address to something like 192.168.55.0/24, will this automatically change my DHCP range and allow new IP's to be leased out after 30 minutes in the new subnet range and in turn allow me to access my home network devices again?
Any advice would be greatly appreciated.
***Update***
I updated my LAN subnet to the new number, pressed save, however before pressing "Apply", I was able to change the DHCP range. Was not as bad as I thought it would be......now for changing the rest of unRaid.

Before pressing "Apply" consider changing address range in outbound NAT rule as well...

Looking at mine, it would appear that I only have two automatic outbound rules, but thanks for the suggestion.
