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…
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…
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…
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)
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…
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…

Hi! I just created a new VLAN and DHCP server with firewall rule and clients are not able to get an IP address. My goal is to have my guest WIFI network (and if I can get this working, my IoT network) on a separate VLAN. I've restarted my switch, firewall…
Hi All,
Good Day!
Is anyone here know how to manually delete the DHCP lease on Sophos firewall.
IP is not in used but still lease on the DHCP entry.
I already set the lease time in 5 minutes but that is not in used still on the DHCP lease entry…
Hi! I've created a new VLAN and DHCP server for it on the firewall. The clients on the VLAN can successfully get an IP address from the DHCP server but cannot resolve websites / or have internet access. Any tips? See below DHCP server config & firewall…
Hi all,
I am new with Sophos, literally day 3 for this to run on my network.
DHCP Server is behaving very strange.
Sometimes it would work flawlessly and other times it would just stop handing out leases.
I have to turn off the status of the…
Ok We have an XGS116 running the latest firmware (upgraded as a part of this process).We have 3 wireless networks configured. The firewall does not have wireless but he have 2 apx320's in place.

Hi,
Just want to ask how the dhcp lease time work. Does the leased start time should be the same when the device got disconnected? or will the leased start time will changed when the device got connected again?
Because as for monitoring the case…
Hey all,
I have a Sophos XG connected to an LTE mc801a router in bridge mode. Every night the mc801a is scheduled to reboot, however Sophos doesn't pick up the new DHCP IP address.
If I change the interface to static, and then back to DHCP, it picks…
Hello,
I have a Sophos Firewall XG330 (SFOS 19.0.0 GA-Build317), with many REDs distributed in different buildings. Each building has his own DHCP RED interface, but I've fixed some IPs. The problem is when someone with a static IP goes to another building…
I am going from a Windows Server DHCP to our Sophos Firewall.
Am I to understand that the Sophos Firewall does not do static IP reservations? Or at least does not do it in the same manner as Windows does?
Does the reserved IP have to be outside of…
