Installing Sophos XG Firewall VPN Client - Sophos Connect

Updated by Bob Pankratz

OS Compatibility: The Sophos Connect VPN client support IPSEC VPNs for macOS and winOS and SSL-VPN for WinOS. If you need SSL-VPN for macOS please see these instructions instead: https://help.technosis.biz/sophos/installing-mac-os-ssl-vpn-client-for-sophos-xg

Pre-Requisites

To use an SSL VPN with macOS, you will need a couple of pieces of info before proceeding:

  • Mac Compatible SSL VPN software. We recommend the Viscosity VPN software based on openVPN.
  • The web address of your Sophos user portal; URL will look similar to:
    https://proxy-st.companydomain.com
    https://proxy-st.companydomain.com:1443
    https://ipaddress:1443
  • The ActiveDirectory Domain name that you are connecting to if you are using a Laptop in and out of the Office for full network access.
  • Your ActiveDirectory username in short-form without the domain. This will be one of the following:
    Firstname, First.Lastname, or FirstinitialLastname
    This will likely be the same name you login to your PC with, in the form of "Domainname\Username" or "Username@domainName.

Download and Install the Sophos Connect Client

  1. Login to your VPN Portal (Your username and password will be the same as your office pc).
Google Chrome is recommended for this step if you have a self-signed security certificate. With a self-signed certificate, you will receive a security certificate warning you will need to use "advanced" > "proceed" to go around the error. This is normal for self-signed free certs.
If you get the warning but don't get an "advanced" button, you can still bypass the warning by typing "thisisunsafe" on your keyboard; you won't need to press enter, and the browser will move forward to the login page.

    • If your firewall administrator has configured a One-Time Password (OTP), in addition to entering your username and password, you must enter your six-digit OTP passcode. You'll see a third input box (under username and password) where you enter the OTP passcode.
    • If your firewall administrator has configured mixed-mode two-factor authentication (2FA), you'll see a third input box (under username and password). You must enter one of the following words: push, phone, sms, or enter a DUO token.
    Sophos Connect attempts to establish the connection and authenticate you.
