Sophos UTM - extra networks behind firewall?

Hello. I currently have everything (desktops & servers) on a single subnet in an office (let’s say 10.10.10.0/24). What is the best way to split this out so that I can put the servers on a separate subnet (say 10.10.20.0/24) and control access via the UTM firewall? Do I need an extra interface on the UTM to achieve this? Or can I just use the LAN interface and add extra IPs? That sounds like the less secure option. I have SG230 appliances. Thanks in advance.

  • Hi and welcome to the UTM Community!

    The answer depends on knowing if your switches support VLANs, then that's the easiest solution.  If not, then it's difficult to know whether your better solution is replacing your switches or using a different interface and adding switches for the new subnet.
