I think I've come across an anomaly that I simply cannot explain. It caught it because a user complained. I remoted into their laptop and ipconfig showed me the ipconfig that I wasn't expecting. I need help untangling this. So I have 2 buildings A and…

I would like to know how DHCP server works on a XG Firewall. Is there any relationship between computer MAC address and the IP address assigned by the Sophos firewall DHCP server?. Address are assigned in a consecutive order? Thanks in advance.

I have a Sophos XG 125 Firewall and recently after updating the latest firmware, I'm having an issue with WAN port of firewall. The firewall's WAN port does not update the IP address automatically. I have to unbind the port and bind the port again to…

Where can I find a description of the messages I find in the networkd.log? I'm looking for how to tell what might be going wrong with the wan dhcp request on my port2 on one of my XGS107's that is unable to renew an ip address. Can I disable the GuestAP…

I had an DHCP renew issue at a site today, but I have seen it at others. This one annoys me because I had to drive an hour to the site. Sophos XGS 87 fed on WAN by FIOS ONT ethernet. Fios rebooted the ONT, because that is what their automated system…

I'm trying to locate the logfile that would track the firewall's own client dhcp request over a WAN connection when trying to get an ip from a Cradlepoint modem? My XG210 (SFOS 19.5.1 MR-1-Build278) is having trouble, but when I connect my laptop to the…

I'm trying to copy a PXE Boot Optin from the DHCP Server of a UTM to Sophos XGS The problem I face is, the Boot Client uses the IP-Address of the Firewall/DHCP Server as TFTP Server instead of the value provided in the Option 66 (Next Server) I tried…

Hello Community Members, Hope all is well on your end. I would like your support concerning PXE boot when the DHCP services are provided by SFOS Firewall. My WDS/PXE server is on a different VLAN and the laptops/desktops are on a different VLAN…

Hi All, We issue DHCP licenses from our Sophos XGS appliance. Since I specify the pool in the DHCP section in the interface... the XGS should know how many leases are available, and since the XGS appliance hands them out, it should know how many leases…

I have a rule that allows DHCP traffic from port 68 UDP to port 67 UDP and in the firewall I see the following in the log: Appliance Access - Denied - Firewall Rule 22 - Rule Name: AllowDHCP - Src IP: 0.0.0.0 - Dst IP: 255.255.255.255 - Src Port 68…

Hi folks, looking to find a way of obtaining information similar to this. DHCP server: ANY (255.255.255.255) Leases: 692 Offers: 1 Requests: 693 Acks : 692 Naks: 0 Declines: 0 Releases: 0 Query: 0 Bad: 0 Forcerenews: 0 Failures: 0 VRF: global DNS0…

Hi, I have been searching the forum. This question has come up many times over the years without an answer. Actually, there is one answer marked as correct stating that DHCP clients never send data to the server. This is obviously incorrect. I…

Dear Sir, I have biometric device which connects to WIFI and IP is released by DHCP in sophos XG 310 firewall. It does not ping to this IP from LAN network, nether i am able to access this device using this dhcp released IP address from browser.. How…

Update (31/01/2023) Back to the drawing board. This has broken again. I have checked the settings in the Cloud Key are set as described below and nothing has changed. My device is set to automatic updates and unfortunatly I didn't record the firmware…

Does anybody have any clever ways to monitor dhcp pools. I have about 8 subnets/pools setup and it would be really helpful to know when a pool runs out of IP's. The log doesn't show that the pool is exhausted, it just doesn't respond to the client's discover…

problem description see here: DHCP Relay over Routing-Based IPsec in SFOS 19 not workin I guess there are no plans to "add this feature" in future? Documentation is missleading: https://docs.sophos.com/nsg/sophos-firewall/19.0/Help/en-us/webhelp…

I have created a DHCP IPv6 Server, but nothing is working. (Nothing getting an IPv6 automatically / nothing talking to its DG) Above is a VM on vcenter not pulling anything with DHCPv6 Sophos is a VM. And the above Ubuntu server screenshot is a…

I'm in the proces of setting up a Sophos XG on an Intel platform and step by step overcoming the differences I encounter from other FW products I have used. I mainly have experience with Untangle and Ubiquiti products. The plan was to onboard all of…

A client has a number of firewalls and 2 AD servers, one on prem and one in Azure. They wish to control IP address assignments in Windows instead of on each firewall. This makes sense as using Central to manage a number of firewalls is slow and somewhat…

Hi, I have setup a DHCP service for a /24 network on a Sophos XGS 136 device. I've also setup an internal DNS (bind) server that contains 2 zones "abc.net" and "internal.abc-software.net". The IP address of the DNS server has been defined in the primary…

Hi, Is there any way to map a static IP to multiple MAC addresses? In UTM it was possible just by adding all the MAC addresses to a host object, and whichever MAC was presented to the DHCP server, it would get that IP address. I get that there are…

Hi all, I'm new with Sophos XG and I apologise if the question is trivial. I've created some VLANs and for each one there is a DHCP server. DHCP servers are configured to announce the Interface IP address as the DNS server but I can't resolve client…
