I have a Juniper SRX220 Firewall.  I am connecting to a Service provider who is running a SOPHOS Software base UTM firewall.
They tell me there is little for them to configure and that they have a couple thousand site to site VPNs connected.  Hence, the problem is back on me.

What happens is the Site to site comes up and everything is working, and then about 15 minutes or so into it the Tunnel goes down and I have to reinitiate the tunnel.
I am at a loss to see any problems.  Anyone seen something similar.  It has to be something simple.   Ive attached a file with some shots of the configuration that I have control of.JuniperScreenshots.docx

We have a UTM Sophos XG 85. The client is having issues with the websites loading very slow. I put another router in all fine.

Any suggestions?
We are running Sophos XG firewalls and need to devise a way to import the appliance SSL certificate so that we can enable secure HTTPS scanning.  This can be difficult to deploy particularly with mobile devices.  I'd like to see if anyone has developed a streamlined way to do this outside of AD GPOs on the Windows systems.
We have students with iPads.

Certain webpages, always in Spanish or Brasilian get blocked and a Content Restricted error will appear.

Very rarely the landing page, usually a subpage.

Our Sophos filtering system has the domains whitelisted for the students but this makes no difference and the logs show the * as Allowed.

Where else can I look? Are there logs or reports for Google safe search?

Any help would be greatly appreciated.
I have a request to give a file/folder encryption software.
I saw Sophos Safeguard but it seems very expensive compare to other softwares.
Anyone knows a better software whch encrypts and password protect the files/folders.
Customer wants to password protect a file and send by email and share the password privately.

Appreciate your advise.
WMIC is working for some users/computers and not for others. We have a Sophos Firewall that uses WMIC for authentication. It works for some users and is not working for some others, I contacted Sophos tech support and after some test, they said that the problem is with my DC server, in which WMI is not working properly. How can I make it work for all users/computers?

(please see a screenshot attached.

We have a Sophos Web Appliance monitoring/filtering traffic on student and staff network.

Content on the student network seems to get blocked randomly.

For example, a the Student could be working in Google Slides. They finish making a presentation on their iPad, then select 'Present' and the page is blocked with a 'Content Restricted' message.

On the staff network the presentation will display.

Another time a wiki page in English is allowed but the same wiki page in Portuguese is blocked.

I am very new to Web Appliance but have some experience with XGs. Where could I start looking to solve these issues?

Many thanks.
Dear Experts,

I have a VMware 6.7.0.

I am trying to deploy a sophos VMW using ovf template on it and it says "A required disk image is missing"

How do I properly deploy ovf template as I only add the virtual_sf.ovf and disk1.ovf file only.

Anyone can guide me on how I should properly do it.
I looking for any free firewall software appliance. (Like the old version of sophos. The new version of Sophos provide only 30 days software appliance)
I don't know if there is any firewall which provide a software appliance free and without time restriction.
Connect to shared drive's and browse through server shares over SSL VPN
Sophos XG 125 UTM Firewall
Windows Server 2008 R2
We have configured our Sophos XG 125 UTM Firewall for SSL VPN.  This will allow our clients to connect into their workplace so they can safely either RDP into their computer OR use the server shared drives.
I've configured this for many of our other clients and have had no issues.  Have also contacted and worked with Sophos Support to confirm it's not a Sophos config issue or VPN issue.  

Our SSL VPN connection is successfully established.  I am able to ping all server IP's as well as their FQDN and get a response.  I am also able to RDP to the required computers.  
I simply cannot browse to the server thrgouh UNC.

I've compared this to our other client's setup's that have the same SSL VPN setup and we have no trouble browsing UNC.  

I also performed a TCP Dump on the Firewall at the time I try to UNC and it shows the requests going to the server but the server does not respond to the request.

I feel that I've ruled out the SSL VPN and Sophos Setup, DNS, Network Discovery, NTFS and File Sharing Permissions.  Any idea's?

How to unblock WSuS traffic from Sophos xg firewall in domain
Hello All,
I am hoping that you can provide me some fresh eyes regarding this issue.

- SBS2011 Virtual Machine, single NIC, DNS configured to point to itself, sole DC
- 7x client machines with workstations only pointing to server for primary DNS, no secondary
- Cyberoam firewall with Sophos OS, latest firmware
- SBS DNS has 4x forwarders (2x ISP, 2x Google) configured to 3 sec timeouts.

All of the workstation clients have been experiencing an internet outage that lasts seconds.  The symptom is that they will go to load a webpage and the page resolution appears to hang.  The result is either a very slow loading webpage that eventually comes up or partially comes up, or a page saying the website could not be resolved.  If they refresh the page, it immediately comes up.

- Assign workstations to only use external DNS (, issue goes away
- Assign workstation to a different gateway, issue goes away
- I installed a new secondary DNS server that pulled its info from the SBS DNS.  This VM was joined to the domain, but not promoted to a DC.  I then moved one workstation to the DNS server and the issue did not resolve.

My thoughts
My concern is that the SBS DNS is somehow corrupt or not working properly.  Is there a way to reset it?  

I could also rebuild the secondary server without pulling the DNS info from the SBS server, but my fear is that it will be missing critical AD required information for the workstations.
I have internet in my building (PPPoEoE), currently, i'm using a linux machine as the router/firewall and I want to migrate to sophos myutm.

when I connect to the internet using linux, I have my default route that just routes to the interface:
ip route add default dev ppp0

The thing is, Sophos doesn't support interface routes for whatever reason, so it's using the PtP remote address, which my ISP has set to The problem is, MY router is, so when it adds the default route, it stuffs everything up.
Sophos runs linux in the background, and I can remove this route and add an interface route and everything starts working again.
The route set by my ISP does the following:
ip route add default via

My ISP says this doesn't matter because it is a PtP route, so it should route, however, it doesn't.

I've had to revert to my linux machine, and looking at the logs, with the relevant lines at the bottom of this text

I expect the remote ip address to be something like rather than

Is my ISP wrong? can someone point me in the direction of the relevant information about this? I've had a look online, and I can't find anything specific.

Dear Experts,
I have an issue lately after upgrading email security appliance. All outbound mails are using my Cisco firewall interface IP and often bounces as my email server public IP is different. Email appliance is Sophos EA.
My email server public IP is
Cisco FW ASA interface public IP
There is n option on sophos to change outbound IP address it takes primary up (internal).
On Cisco I have all SMTP traffic going out via but still traffic from sophos EA goes out via 196.
What should I do on Cisco ASA to make sophos ( internal IP to use for all outbound traffic.
We have Sophos UTM 9 that is providing dhcp. There are maybe 50 laptops in use.  There are access points through out the two buildings. The two building are connected with hp filber switches. The access points are meraki but there are a couple of older cisco access points.  I keeping getting calls about users not being able to connect to the internet. I find that they are connected to the wireless but the connection has a yellow bang symbol over it.  I release the address, flush the dns, disconnect and reconnect to the wireless but nothing fixes the issue.  The only thing that works in these instances is to set a static ip and dns.  Does anyone have a suggestion on fixing this or an idea of what is causing this?
need to install a sophos firewall. there is a cisco router that the ISP is plugged into and it has quite a bit of config on it. we are wanting to use the firewall primarily for webfiltering traffic. We would like to place it behind the cisco router. not exactly sure how to get web traffic to go through the firewall to be blocked/allowed. The client server runs DHCP and broadcasts the gateway as the internal ip of the router.
