General Discussion / Re: No internet connection after changing LAN IP
May 28, 2025, 04:48:49 PM
Ok so I guess the main issue is that I didn't use a distinct subnet for WAN and LAN, and the fact that it did even worked to begin with is only due to luck.
I'll change the subnet and keep you updated.
Thank you for your help.

General Discussion / No internet connection after changing LAN IP
May 28, 2025, 04:05:26 PM
I just installed OPNsense on a Proxmox VM to try it out.
My goal is to have OPNsense between my ISP router and the rest of my network.
Out of the box everything seemed to work fine, but to make things easier for me, I wanted to change the IP address of the LAN interface from the default 192.168.1.1 to 192.168.1.254, because this is the IP of my ISP router and I thought that it would allow me to connect all my devices to the LAN without having to change the configuration of the ones with static IP because the gateway address would be the same as before.
But after doing that, I can't access internet anymore from the LAN side. I can access the OPNsense web UI, I can ping google.fr from opnsense, but from a computer on the LAN side I can't even ping 8.8.8.8.
I'm new to this so I might be missing something obvious, but I've been looking for it four hours and I can't figure it out.
Do you have any idea of what could cause this issue ?
Thank you
Edit : I forgot to add that I made sure to renew the IP settings from the client to get new informations from the DHCP, the gateway IP has been updated as expected but that did not help.
