Folks I have a need to change the internal subnet on my UTM from a 192.168.2.x to a 192.168.3.x due to a site to site VPN subnet issue. I made the mistake of simply changing the internal interface IP but found myself locked out of the Webadmin interface. Fortunately I had vpn configured and I was able to login to the Webadmin interface that way. Upon logging in to Webadmin I realized I was not able to change the Internal Network Definition from the old subnet to the new one as it did not allow editing. How is this done? Thanks!
