Hi there, i have the following setup: UTM 9.5 which runs between the modem and the wlan router/switch. UTM is set up in transparent mode. I run a DNS "server"/internal forwarder (pihole, details at https://pi-hole.net/ ) at 192.168.0.115 on a raspberry…

Hi, I am using Sophos UTM also as my DHCP server. I have IP addresses available from 192.168.2.1 to 192.168.2.255 (I believe this range of 256 IP addresses are default because of subnet mask 24) I went into DHCP and then on servers tab, I see the…

Hi everyone, I know there are threads addressing Chromecast issues, but I have tried all of the suggestions in those threads and can't seem to get mine working with the UTM. My HP printer, cell phone, and Mac Book all pick up wifi just fine, but Chromecast…

Hi all, hopefully a simple question: Can you centralize the host-lists when using only static mac-mappings for dhcp leases in multiple locations? Basically I set up the DHCP in a testlab to prevent connections of private/unwanted devices. To do so I…

I've been doing some network refreshing over the past week. Today I spun up a new DHCP server pointing to new DNS servers. The setup is pretty straightforward - we have two VLANs phones and data. The new DHCP and DNS Servers worked fine on the Data…

Is there a way to define multiple WINS servers in the DHCP Server for Sophos UTM 9 ? The 'Advanced Options' section in the DHCP Server definition will only take one. I have also tried adding option 44 in the Options tab (which should allow an IP address…

Hi, I'm soon rolling out a bunch of RED 10s and have a question regarding the WAN setup and RED Fallback. In UTM9 WAN Settings for REDs you can setup a Static IP. I was wondering wether i can input a public IP or not (so i don't need a Router in…

Hi, I have an SG230 with a couple LANs: Staff and Guest. They work fine and can get out to the internet. I'm trying to add a third LAN. I seem to have all the settings the same as the other two (different subnet of course) but for some reason at cannot…

Hi, I'm a newbe. So thanks for your patience. We are a school. We have an Internet connection with 5 public IPs (xx.xx.xx.202 to 206 - same gateway). We are using UTM 9 as our firewall. Our main network gets DHCP from a Windows box (192.168.x…

Hello, I'm running Sophos UTM 9.503-4 on a pcengines APU board behind a FRITZ!Box Fon WLAN 7360. The UTM is configured as exposed host on the Fritz!Box and the UTM provides DHCP and DNS for my LAN. There are no other DHCP or DNS servers and I don't…

I tried to expand my network. At the moment it is all wired. I have a ASUS RT-AC87U consumer grade router. It's possible to set it into access point mode. I did so. Furthermore, I gave it a static IP in the range I wanted to use for the WLAN-VLAN. My…

I've recently implemented the sophos UTM firewall running as a VM under esxi on a minipc in place of a standalone router/ap. The obi's are defined in the UTM's DHCP server with specific IP's under static assignments. During testing, I changed the assigned…

I'm having an issue with a new device obtaining a DHCP lease. The client is a LiftMaster MyQ Internet Gateway device and a static IP can't be set. I see the request hit the DHCP log but it just loops between discover and offer every 5 seconds (log below…

Hey guys! I've got an XG105, and can't find where to associate addresses to Mac addresses (coming from a Cisco ISA series here). Where's that menu option? I'm wallowing around in Configure > Network > DHCP and am feeling pretty daft! Thanks!

Hello, Has anyone figured out a way to bind through DHCP a specific list or pool of IPs (ex. 192.168.1.1 to 192.168.1.20) to a specific list of predefined MAC addresses? The idea is that the MAC addresses in the list or group always get an IP from the…

Hello, We're in the beginning stages of rolling out IP phones and we want to use a different DHCP scope for phones as opposed to workstations. Our office is only roughly 40 users so I don't think VLANs are worth the effort so I wondering if someone with…
