New to Sophos UTM. Question about Internal DHCP.

Hello, I just switched from pfSense to Sophos UTM 9 in my home lab a couple of nights ago. I had about a dozen virtual machines running when I made the switch, and I need reconfigure static IPs for my two ESXi hosts and vCenter.  They are all showing up in the Sophos IPv4 Lease table as different IP addresses and I cannot ping them or resolve their FQDN.  Is there a way to manually change them back to what I had them at before?  My subnet is 192.168.1.1/24, DHCP rage is 192.168.1.50-254.   Thank you.

  • To get your static mappings back for your devices. Log in to your UTM and go to the Network Services, from there go to DHCP, and then at the top you'll see several tabs you can click on. Go to IPv4 Lease Table, from there, you can click on Make static and it will open up a new box for static options. 

    From there, it will let you put in a name, a comment along with having the MAC address, DNS Hostname and IP already filled out for you. You can of course change the IPv4 address to one of your choosing along with the DNS Hostname. 

    Hopefully that is what you were looking for and helps.
