Using Sophos Connect VPN Client

Hey everyone,

I wanted to highlight one of the features listed in XG v17.5 - Sophos Connect. Sophos Connect is a new IPsec VPN client, included with XG v17.5. This is a preview release, where we decided to make the client available now, before we've made all of the XG improvements we are planning. The client, as it stands now, is a cross platform (Windows and Mac) IPsec client with a simple user interface, and a compelling set of features, that are finished, and available for use now. We didn't want to sit on that while waiting for the rest of our plans to be completed, so we decided to get that out to you sooner, even though the total admin user experience still needs a few significant improvements. 

In XG, you'll notice that the Cisco VPN tab under VPN, has been re-named Sophos Connect, and now offers a download for the new IPsec clients and admin utility. While you can create a split tunnel remote access policy on the IPsec tab, this doesn't yet offer a client IP range. So clients will connect and communicate over the tunnel, using whatever IP they are using locally, on the network they're in. While this might work in some cases, it runs into problems, as soon as your users are connected from a subnet that conflicts with a network being accessed over the tunnel. Having visited a hotel or two that gave out addresses in massive 10.0.0.0/8 subnet ranges, the possibility of a conflict using that configuration is pretty significant. Meanwhile, the feature originally built to work with the now-antiquated Cisco IPsec VPN client solves this, and does offer a client IP range, but doesn't allow you to configure a split tunnel. Since the Cisco client is pretty outdated now, we decided to re-purpose that feature for now, and use it as the preferred method for configuring Sophos Connect. 

This makes for a more robust configuration, but the policy generated by that feature, only offers a full-tunnel. While that may be enough in some cases, most of you are looking for a VPN client that allows split tunneling. The tunnel will support split tunneling, but the UI doesn't yet offer that capability. We could slap in the feature, but we also want to move to a more modern method of pushing policy from the firewall when the tunnel connects, rather than leaving all of that up to the config file. So for now, we've taken a short-cut, (this is an early access release after all :) ) and provided a simple policy editor utility. This also let us expose some of the other great features Sophos Connect offers, like the ability to send Security Heartbeats over the tunnel, or an auto-connect when remote capability. 

Ultimately, we will resolve these limits in XG directly, but for the time being, Sophos Connect Admin will let you customize your policies then deploy them to your users.  It's a temporary solution needed to let you use these features, until we can add them into the firewall itself, and one of the big reasons this client will remain as a long term early access release, after 17.5 goes to GA. 

The client is free, and will remain free in the future, and is available to download from within XG today. The client is now available for early access, so we look forward to your testing and feedback. At the end of the XG EAP, the client code should also be considered at a GA quality at that time, but because of the limits I mentioned earlier, we'll continue to offer it as a longer term EAP release, until some time mid next year. 

The download is in the firewall now, under VPN > Sophos Connect client. Also, if you've just updated to v17.5, be sure the firewall has downloaded the client, under Backup & Firmware > Pattern updates, before you try to grab a copy. The package you'll get from the firewall will contain three programs. Sophos Connect for Windows, Sophos Connect for Mac, and Sophos Connect Admin, which is only available for windows. 

You can find instructions in installing and troubleshooting the client, here: https://docs.sophos.com/nsg/sophos-connect/help/en-us/nsg/scon/concepts/AboutSophosConnect.html

Looking forward to your feedback, and happy testing!

  • It is currently still missing 2 very important requirements.

    1 - MSGina support. Corporate clients need simplistic logon features and the ability to execute logon scripts.

    2 - Multiple IP range support. Corporate clients can have multiple address ranges behind their Sophos firewall. The VPN client needs to incorporate that.

     

    The client may be free, but it is still years behind others.

    Thankfully the green bow client still ticks all the boxes.
