Dynamic DNS is a service you can use to make a device with a dynamically allocated IP accessible from the outside in. Common Dynamic DNS providers include DynDNS, ZoneEdit, EasyDNS, and DynAccess. Sophos XG Firewall supports these four Dynamic DNS providers, but it also includes a fifth provider simply called Sophos, and the great news is it’s free! This article takes you through configuring Sophos XG’s free Dynamic DNS service.
I just happened to have an ageing Sophos UTM SG115 in our spare parts / swap out stock and thought I’d see if it could be repurposed (or rather re-imagined) as a Virtual Server running multiple virtual devices. Wouldn’t it be cool to have Sophos UTM and Sophos SUM running on the same box? Let’s give it a go!
This article describes how to use Fastvue Sophos Reporter to report on machines potentially infected with WannaCry Ransomware on your network. The first and second variations of WannaCry ransomware access specific domains before the installation phase. You can therefore report on all machines that have accessed these domains to help identify potentially infected machines.
The WannaCry Ransomware infection is currently causing havoc around the globe. Fortunately there are security patches available from Microsoft that fix the underlying security hole in SMB that the ransomware exploits. However it is a good idea to keep an eye on any machines on your network that are or were infected.
With Fastvue Sophos Reporter, you can create a simple alert to receive instant notifications when machines on your network make requests to the domains that WannaCry accesses before installing.
We’re pleased to announce that Fastvue Sophos Reporter now supports Sophos XG, providing the same great web usage reporting features for Sophos XG networks that Sophos UTM (SG) users have enjoyed for over three years!
When it comes to true web usage reporting, there’s nothing quite like Fastvue Sophos Reporter and its Site Clean engine, and now Sophos XG users […]
Sophos UTM enables you to specify multiple destination syslog servers, but they will all receive the same syslog information. This is inefficient when some of your syslog servers only require certain log messages for specific purposes.
This article explains how to configure syslog-ng to filter and forward Sophos UTM syslog data to multiple syslog servers with different data requirements.
In a previous article we covered how to use Sophos UTM to establish an IPSEC VPN tunnel. IPSEC VPNs are great for a number of reasons, but they have a big drawback when it comes to NAT traversal. While Sophos UTM supports NAT-t, where one side is behind a NAT, you run into connectivity issues when both sides are […]
Anyone who has ever had to deliver application traffic over a WAN has no doubt run into the issue of trying to determine how their application would perform for a remote user.
In this article I will outline some of the issues with WAN delivery, and then move on to some easy WAN emulation tools to help simulate the conditions […]
Sophos UTM is a great Reverse Proxy solution. However, it currently lacks the capability to redirect a request.
There are several reasons you might want to redirect a site, but the most common scenario is to temporarily take a site offline and display a ‘Site Under Maintenance’ page instead. This is far better for a public site than to simply drop […]
This article highlights an issue in Sophos UTM where user information is not logged when files are downloaded and scanned by Sophos UTM. It shows how this issue affects reports (both the the web usage reports on Sophos UTM, and in Fastvue Sophos Reporter), and how to work around the issue.
