I am looking at a replacement for our aging Cyberoam UTM. One of our options is the Sophos X330, which appears to be a good upgrade path for my requirements.

Has anyone used Cyberoam and the moved to Sophos? I am curious if there are setup and managing similarities. Seeing as Sophos acquired Cyberoam a few years ago, I was wondering if the Sophos UTM would be familiar in some way after using Cyberoam. Maybe they had adopted various features, and so the appliance would be familiar in how it was setup.

Would you consider the Sophos XG series easy to setup and deploy? I don't really want to get a technician in to setup the system on the new UTM. I setup our Cyberoam and continue to manage it without a problem, so I am hoping to do this with whichever new one we choose.

Any other thoughts about your positive or negative experience with Sophos UTM's would be appreciated?

We are currently deploying Mimecast to our environment. We had setup the journaling and send connectors. We found that all the journaled traffic was causing a backlog in our on premise Sophos Email appliance. My question is, can I configure the primary send connector to our email domains instead of *, and configure the mimecast send connector for it's domain @journal.ourdomain.com.au, or is this going to cause issues?

Outlook 2007...
Recieving but NOT sending emails...
Occasional Secuirty Certificate cannot be Verified...

My mother in law...age 95 is active on her PC...She uses Outlook and is fairly familiar with it...We POP Gmail...

She has been using this PC with W7 and Outlook 2007 for about 8 years...
She lives in an assisted care facility...

About 2 weeks ago she started getting Security Certificate cannot be Verified...
Relates to Sophos...says a mismatch in the SSL port...and Outlook will NOT send email...but she recieves email ok...

I cleaned it up...reinstalled Office 2007...and got the same problem...no joy...

So...I took it to my shop...and discovered that Outlook worked just fine on MY internet connection...

BUT....I rebuild the PC anyway and installed W10...re-installed Outlook 2007...connected her PST file and everything is working perfectly on MY internet...

I set it up again in her apartment at the assisted care facility and Outlook will NOT send email...I had the facilities maintenance guy try...and we cannot get it working...
Internet is fine...if I go to Gmai webmail her email works just fine...

So...It seems to be an Outlook issue on the facilities network...

So...on Gmail the SMTP port is 587....what do you think the chances are that the IT company that handles the assisted care facility closed port 587 on the router...???

Or...is there some possible other reason for the issue...

Many thanks in advance...

Hi all,

We have a VPN tunnel between two Sophos firewalls.

Location A = 10.102.0.0/24, 192.168.99.0/24 (VLAN99)
Location B = 10.102.1.0/24

The VPN tunnel is UP and communication between the main networks is working properly.

From site B, however, the DMZ network (VLAN99) in site A is only limited reachable.


From Site B -> I can ping the gateway (192.168.99.1) but the Printer (192.168.99.14) is not reachable. I should say only the gateway is reachable everything else can't be reached through the VPN tunnel from side b.

I have attached a screenshot of the VPN tunnel configuration of both sites.

Thanks in advance.

I have a couple of machines that are not able to browse to HTTP sites at a remote site where that I have established a PPTP VPN to that site (via the OS). I can ping the respective IP address fine however HTTP browsing does not work. I am of great suspicion that this is something in our Sophos UTM as I can browse to the HTTP sites on my laptop via cellular connection fine (effectively bypassing the Sophos UTM).

I am not using 'use default gateway on remote network' yet I am unable to packet capture (in the Sophos UTM) any traffic going via the PPTP VPN to the remote site.

I've worked with Sophos UTMs (ex Cyberoam) for a number of years now and I cannot see anything obvious where anything would be being blocked or dropped. Everything is open. Nothing has been modified recently that would prevent this, and it only stopped in the last few months (yes I've been slack).

Has anyone experienced similar issues?

Client is using a Sophos XG Firewall to filter email. The XG had been configured in MTA mode and had been working with an Exchange 2010 server running on  Server 2008R2 for about 1 year. Over the weekend, the client updated the firmware from SFOS17.0.2 MR-2, to SFOS 1706 MR-6. After the update, Sophos log reported that email had been delivered from the Sophos to Exchange, but was not received in the client mailboxes.

A call to Sophos support resulted in turning the Sophos from MTA mode to Legacy mode which achieved the objective of Email being filtered and delivered to user mailboxes, however, any reports generated by the XG (i.e. Quarantine Digest) are not being delivered from the XG to Exchange.

One symptom which the Sophos tech was unable to explain was that he was able to telnet from a workstation into the Exchange server, and get a response, but not from the XG into the Exchange server. We would get "Connection refused". When reviewing the Sophos logs (after the change to Legacy mode), System Log reports "Fail to send mail: Cannot connect to mail server servername.domainname.com:25, when attempting to send a test from the XG.

There have been no changes to the email server and the only change is the XG firmware. Has anyone else experienced this issue?

Inherited a new client with a Sophos appliance.  The UTM 9 so far seems to be a great device.  That being said, I am trying to turn off filtering for a specific endpoint.  Even though it is in the "allow access", when I am on that endpoint it still get re-directed to a webpage hosted on the appliance and is expecting to want some sort of authentication.  Are there good tutorials on how to manage Sophos?

We had a user whose laptop was infected with ransomware, and that led me to look into the solution to it, and our backup system.
Fortunately, he was not connected to the company network, so the files were only locked in his laptop.
Free ransomware removal tool from TrendMicro, and someone else did not work.

1. What is the best removal tool?

I am looking into Sophos. They have Enterprise Malware Removal Tool that can take care of Ransomware. We use their anti-virus software, so theirs caught my eye.

2. What is the best backup strategy?

I had a IT admin friend, and his system got infected. He spent $30K to get his files back from the servers, and what was interesting was that the ransomware did not manifest itself right away. It was like 2 or 3 days later.
Right now, my servers are backed up fully every night to a USB drive. I have only 3 servers. No incremental or differential. I'd like to know how people backup a couple of terabyte data these days. Tape systems were used in the past, and each day manually or automatically different tapes were used. Do people do this even in 2018? I only used it 10 years ago.

These can have multiple full backups, and each time are they totally offline from each other? I hear that Ransomware can go into other resources in the same LAN. Then I need a backup system that can backup multiple generations (like daily), and they need to be completely …

Hi all,

I'm looking for a bit of help getting started with my HP 1820-24g switch .

my network plan :

sophos router eth1(lan 192.168.0.1/24) and i configured the sophos router so : new interface eth4 (192.168.2.1/24) mit VLAN ID :10 function.

i also sophos router configured dhcp scopes for 192.168.2.100- to 200

so i connected sophos eth4 lan cable  -->switch port 1


so i have the native vlan 1, and  vlan 10(port 1-10 tagged) for lan  on the router.

my problem are:
1. if i change sophos interface(eth4)  Vlan funtion to only ethernet and i connect my laptop port 7 then get my laptop IP from sophos router dhcp server.

2.if i change sophos inteface (eth4) only Vlan fuction (vlan 10),then my laptop gets no ip from sophos dhcp server.

any idea and help?
Thank you

For the patch of the chip vulnerability, can I just download the patch from microsoft and install it on all servers and workstations rather than use windows update?  I have a couple servers and 20 workstations.  Also, I noticed that you have to be careful with antivirus because of a registry entry.  Can someone help me out with this issue, I use SOPHOS antivirus and the link below details what they are doing to work with the MS patch.  I think it says that SOPHOS works with the patch but I am not entirely sure.  Better safe than sorry.  Here is the link:    https://community.sophos.com/kb/en-us/128053

Hi All,
We have two sites linked via BT routers and each site has its own UTM and fail over simple diagram below.

WAN                                         WAN
  |                                              |
Router                                     Router
  |                                               |
UTM                                         UTM
  |                                               |
Lan - Router -WAN - Router - LAN

So we have a site link and two sites with Primary/DR with fail over routers

The primary site UTM has IP : 194.72.126.66 GW : 194.72.126.65
The primary sites internet works fine

The secondary DR site UTm has IP : 194.74.139.67 GW : 194.72.126.65
I cannot get out to the internet from this UTM

BT have said there is no issue with the routers and the failover is working on the routers.   Below is the information BT have provided me concerning the IP address allocation.

I have recently taken over this position and I'm under the impression this has never worked any ideas why the second UTM at the DR site cannot get  onto the internet?

Regards

Hi

Were looking at this in detail.  Would like to audit and monitor data that is being driven by users, so services and apps they are using, and what they are sending via email in particular.
Tried exchange online DLP - pants.
Mimecast DLP - pants
Sophos DLP - seems ok, but not great.

Anything else out there?

Thanks

I have a server with a Hyper-V role and virtual machines and a firewall sophos installed.

I would like to create a rule in which when a client (out of the internal network) want to connect to remote connection then this user need to transfer to a specific virtual machine (not to the host server).

How to create this rule?

Dear Wizards, can we have some solutions (Open source) to setup networking environment for startup (small) company. We knew some things like:
- Firewall/Router: Sophos XG Home, pfSense
- Storage: FreeNAS, XPenology
- PC: Ubuntu, OpenOfficce

How about the Switch? Is there any Open Source ISO file that we can use to simulate the Switch (let's say Cisco :))

Many thanks!

Set-up issues


I will preface this by saying I had a UTM120 for three years with the UTM9 OS and right now thinking boy I miss those days.  I was told that my appliance was nearing end-of-life so to renew licensing I went with the XG115.  I had configured UTM9 on my own and generated help desk cases if issues arose.  This appliance is quite a bit different.  Firmware XG115 (SFOS 17.0.0 GA) so on the latest firmware.

What I am trying to resolve right now is that any type of web surfing is extremely painful.  I have an on-premise Exchange server so port 443 is being forwarded to it but I also have the default network rule of WAN to LAN all ports and all services are open.  I have a similar network rule that WAN to LAN port 443 is open thinking of other workstations that initiate SSL traffic it will find its way back to the device that initiated the traffic.  Let's face it.  Most web sites are https.  I am constantly being warned that the certificate cannot be verified and I have to click to still access the site or create an exception for the site depending on the browser.  I cannot log in using an account to any web site.  Some sites I can't even create the exception in Firefox.  I can't use the StartPage search engine.  Amazon looks like crap.  No pictures and just a bunch of links.

A little bit on the network.  Uverse gateway goes to a Cisco ASA appliance that I consider my perimeter (and why not have another layer of defense !).  The XG is in bridge mode.  For a …

I've recently installed Sophos XG230 UTMs on two campuses. Now our Sharp copiers could no longer scan to email.

They SMTP through a gmail account.

I know the user email and password are correct but we get a Error [3332]:  Authentication type not supported.
 
When tested with 'no authentication' connection to SMTP server is fine.

Whilst testing I have allowed all outbound traffic.

Any help would be greatly appreciated.

Dear Experts, we have 1000 users located at multiple sites.
- The Headquarter office includes 400 users, has Cisco Router 3925, not yet Firewall.
- Site A includes 200 users, has Sophos Firewall.
- Each of Site B, C, D, E has 100 users, only has Modem Internet, not yet Firewall

In Headquarter, the AD server (Win Server 2012R2) is ready but we are not sure about the method to join domain for ALL users. We have several questions as below:

1. MPLS-VPN leasdline and VPN connection, which one is better in terms of performance and cost?

2. In case we choose VPN connection, should we choose Site-to-Site VPN or Remote-Access VPN, and why? Which devices should we buy?

3. As my understanding, in VPN connection, the users who connected will use the Internet connection from VPN server, is it right? If so, will the VPN connection is suitable for 1000 users?

4. For the Domain diagram, which model should we use for high performance and availability? We intend to install Addition DC in Headquarter and RODC in each site? Is it okay?

5. In Headquarter, all servers are VM and we have Veeam 9.5 to backup, but in sites servers are physical. Which backup software is the best for physical AD machines?
