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,
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…
Hi folks,

Hello Community,
we have many L2TP-VPN Users and the /24 IP Scope is too small for all our VPN Users. If I read the documentation right, it is not possible to use a lager pool then /24. For us a /23 Pool will fit. Actually, we use a mix of SSLVPN and…
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…
Hello,
I found this 12 year old thread,
Block certain mac address to get ip from dhcp pool
and would like to know if it is now possible to prevent the assignment of IP addresses to specific MAC addresses.
Thanks
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…

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:

Hello,
I am using the following:
- SG125 with latest firmware 9.713-19
- APX320 (Wireless Access point)
I use the Eth2 on SG125 that is connected to a device that is supplying a DCHP Server. It is required for a new project.
The APX320 is…
Would it be possible and would it be a good idea to add the capability for Clientless Users to be designated via MAC address rather than IP address? That is, in the IPv6 world. where a machine can have many concurrent and past (but not yet invalid) IP…
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…
Hello everyone, i need some help to troubleshot my problem. I have a virtual machine with Sophos FW home installed. i wanted to use some AP55 leftover i have at home and configure a couple of wireless networks with some VLANs. The problem i'm facing is…
Google searching not successful; how do I set up the DHCP server "dns settings" to push from an XG to a remote Red60 (i.e. client laptop needs to see our domain suffix + name servers)
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…
Yesterday we had a problem where a couple of computers were not receiving an IP address from our DHCP server which lives on our XG330. I disabled the pool for a couple seconds and then re-enabled it and those systems were able to get an IP. My assumption…
