Understanding the Sophos Connect Client

The Sophos Connect Client is key for setting up an SSL VPN connection. It’s great because it supports IPsec remote access VPN and SSL VPN. This means it can meet different network needs⁴. You can easily get the Sophos Connect Client from the user portal or the web admin console⁵.

This VPN client has many features to improve security and connectivity. For example, it has files for both macOS (IPsec only) and Windows (IPsec and SSL VPN). But, remember that SSL VPN isn’t for macOS or mobile devices⁴. You can also import SSL VPN connections with a .pro file or download a .ovpn file⁴.

It’s important to check if the Sophos Connect Client works with your devices before you start. Older versions could set up IPsec connections with files, but newer ones use provisioning files⁴⁵. If Sophos Connect doesn’t work with your device, you might want to use OpenVPN Connect instead.

Preliminary Configuration Steps

Setting up a Sophos SSL VPN requires important steps before users can connect and access resources. First, I set up IP hosts for local subnets. This lets remote clients reach the needed network resources. Then, I explain how to make user groups and users in the Sophos firewall.

This is key for setting access quotas and permissions that fit my company’s remote access rules.

Configuring IP Hosts for Local Subnets

Setting up IP hosts means defining the local subnets for remote users. This includes:

• Identifying the local subnet ranges that remote users will use.
• Configuring the firewall to allow these IP hosts.
• Adjusting settings to manage session types effectively, with IKE Keep-Alive intervals from 10 to 300 seconds⁶.

Creating User Groups and Users

Next, I create user groups and users in the firewall. This helps manage access levels well. Here’s what I do:

1. Set up user groups based on needed functionality and access level.
2. Assign users to these groups, making sure each has the right privileges.
3. Specify access roles that match the set permissions in the organization’s policies.

This early VPN setup keeps security high while giving users the access they need. For instance, choosing between RADIUS or LDAP for authorization affects how well user groups scale⁷⁸.

Importing the Configuration File

Importing the configuration file is key to accessing the VPN. Here’s how:

1. Open the Sophos Connect client.
2. Select the option to import a configuration file.
3. Pick the .ovpn file given by your administrator.
4. Enter your user details when prompted.

After importing the file, you should connect to the VPN automatically¹⁰. You’ll get unlimited internet as part of the Remote SSL VPN group benefits¹. Make sure the IP address range for SSL VPN clients is private¹.

Follow these steps to securely and efficiently access the Sophos SSL VPN¹⁰¹⁹.

Establishing a Remote Access Connection

To start, I make sure I’ve installed the Sophos Connect client and imported the needed config file. Then, I log in with my credentials. This is key for safely accessing my company’s network from anywhere.

Next, I set up the SSL VPN policy right. This lets remote users connect and direct all their internet traffic through our firewall. In full tunnel mode, all data from remote users goes through the firewall, making it safer¹¹.

Before I move on, I check the global settings carefully. I decide if I want to allow VPN for all sites or just some. Sometimes, I use the SSL VPN remote access assistant to make policies automatically – it saves a lot of time¹².

It’s also important that users can download the client and files from different places. I keep an eye on the authentication settings too. Using local methods in the Sophos Firewall helps me make sure the connections are reliable¹¹.

With everything set up right, I find that remote access boosts my work and keeps my data safe. Knowing how to manage the firewall, authentication, and global settings helps me connect easily and securely.

In short, getting ready with my SSL VPN setup makes remote access smooth and secure. I make sure to set up the firewall, authentication, and global settings correctly. This way, I can connect to VPN whenever I need to.

Setting Up a Firewall Rule

Ensuring my users have easy VPN access is key. Setting up the right firewall rules is essential for secure remote access. The Sophos Firewall lets me set up rules for SSL VPN traffic, which is vital for security and performance.

Adding Firewall Rules for VPN Access

First, I make sure all SSL VPN connections go through the firewall. This means setting up specific settings and configurations. Here’s what I do:

1. Open the Sophos Firewall interface and go to the firewall rule settings.
2. Create a new firewall rule, picking source zones, networks, destination zones, and networks for SSL VPN traffic.
3. Ensure the rules match the traffic flow. When users connect remotely with the Sophos Connect client, traffic must be allowed from the WAN zone¹¹.
4. Check the rule order, as Sophos Firewall checks rules in sequence. Sometimes, I need to move the new rule to fit my needs¹³.
5. Make sure the authentication server settings are correct, ensuring VPN portal authentication works right¹⁴.

I also enable device access settings to let users connect to local subnet resources via the SSL VPN. This is crucial for giving access only to needed services for my remote users¹¹.

Checking Authentication Methods

In SSL VPN security, checking how users log in is key. Make sure the right servers are set up, like local ones or those linked to Active Directory. Often, Office 365 users use two tokens: one for Sophos SSL VPN and another for Office 365¹⁵. Using more than one way to prove who you are, called multifactor authentication, is common. This is true when setting up Sophos XG for SSL VPN and UserPortal access¹⁵.

For better security, I suggest using the NPS Extension for Azure MFA. It makes logging in much safer¹⁵. Tools like Microsoft Authenticator make signing in easy, showing how important it is to keep security easy for users¹⁵. Using just one token makes it easier for IT and users, which is key for smooth operations¹⁵.

When adding Rublon Multi-Factor Authentication, remember you need an outside Identity Provider like Microsoft Active Directory or FreeRADIUS¹⁶. The Rublon Authentication Proxy must be set up right to make MFA work well with services like Sophos SSL VPN¹⁶. After setting up MFA, test it by trying to connect to VPNs and the User Portal to make sure it works¹⁶.

Changing timeout settings to 3 to 15 seconds can make logging in faster¹⁵. It’s important to adjust RADIUS client and network policy settings. This ensures everyone is checked before they can get in¹⁵.

Device Access Settings for Sophos SSL VPN

Setting up Sophos SSL VPN for device access is crucial for secure remote connections. It’s important to ensure users can connect easily and securely. Configurations should allow for different access zones and make downloading VPN clients and settings simple from a user portal. This improves user experience and strengthens connection security.

Configuring Access for Remote Users

Remote users’ access can be customized with specific settings. For example, the HTTPS port for the VPN portal is set to 443, and the user portal uses port 4443¹⁷. These ports help guide access routes for a smooth connection.

It’s key to consider multi-factor authentication (MFA) for extra security on the VPN portal¹⁷. Also, configuring IPv4 and IPv6 settings helps support various devices. The IPv4 lease range controls IP address allocation to SSL VPN clients, boosting communication efficiency¹⁸.

Security can be enhanced by choosing the right cryptographic settings, like encryption and authentication algorithms. It’s also vital to set rules for disconnecting inactive or dead peers to keep the network secure. This ensures users don’t stay connected too long¹⁸. Compressing SSL VPN traffic also improves performance, making connections faster for remote users.

Effective device access settings and detailed VPN configuration ensure remote users can connect securely and efficiently. This approach supports both connectivity and reliability across different remote access scenarios¹⁹¹⁷¹⁸.
