Instruction: Sophos Firewall explicit proxy authentication failure troubleshooting

Explanation: AI-generated knowledge about Sophos Firewall explicit proxy authentication failure troubleshooting

Output:
Based on the provided reference materials, I will provide a detailed answer to the query.

An explicit proxy configuration on Sophos Firewall can cause authentication failures if not set up correctly. The reference material [1] suggests that to avoid clients seeing a popup for authentication, configuring Sophos Firewall as an explicit proxy in the browser using the internal hostname of the firewall that is in the domain is recommended. However, this alone may not be sufficient to troubleshoot authentication failures.

The reference material [5] provides a general outline for troubleshooting authentication failures on Sophos Firewall. However, it does not specifically address explicit proxy configuration issues.

To investigate explicit proxy authentication failure issues, we need to examine the configuration and logs more closely.

From the provided logs in [4], we can see that the OAuth2 authentication flow is successful, and the user is authenticated via OAuth2: Session{email:lfox@trainingdemo.xyz user: PreferredUsername: token:true id_token:true created:2022-11-07 09:43:20.5774564 +0000 GMT m=+4975.008422001 expires:2022-11-07 10:55:02 +0000 GMT refresh_token:true groups:[US ZTNA_ALL IT]}. However, the logs also indicate that multiple cookies are required for this session as it exceeds the 4kb cookie limit. Please use server side session storage (eg. Redis) instead.

However, the logs do not explicitly show any issues with explicit proxy configuration.

To troubleshoot explicit proxy authentication failures, we can try the following steps:
1. Verify that the internal hostname of the firewall is correctly configured as the proxy server in the browser.
2. Check the Sophos Firewall logs for any errors or warnings related to explicit proxy configuration.
3. Ensure that the OAuth2 client ID and secret are correctly configured on the Sophos Firewall.
4. Test the authentication flow using a tool like Postman or cURL to simulate the OAuth2 flow and identify any issues.

If none of these steps resolve the issue, further investigation may be required, including examining the Sophos Firewall configuration, browser settings, and any third-party applications that may be interfering with the authentication flow.

It is also worth noting that the reference material [2] suggests that Sophos Firewall can authenticate multiple different users coming from the same source IP address when their proxy settings are configured to use the Sophos Firewall as an explicit proxy. This feature may not be directly related to troubleshooting explicit proxy authentication failures, but it highlights the complexity of managing authentication flows in a network environment.

In summary, explicit proxy authentication failures on Sophos Firewall can be challenging to troubleshoot and require a thorough investigation of the configuration, logs, and application interactions. The above steps are recommended as a starting point for troubleshooting, but further investigation may be necessary depending on the specific circumstances.

3.  Test proxy settings: Utilize the Advanced Shell to test proxy settings and ensure they are correctly configured.
4.  Consult Sophos documentation: Reach out to Sophos support or consult their official documentation for specific guidance on troubleshooting PAC file-related issues.

Regarding the reduction in throughput with a proxy (up to 25% as mentioned in FW4020 20.0v2 Troubleshooting Web Scanning on Sophos Firewall.pdf), this might be relevant when testing proxy settings but may not directly address the query at hand.

If you have any additional information or context regarding the PAC file issue, I'd be happy to try and provide a more tailored solution.


Instruction: Sophos Firewall captive portal bypass for authenticated users troubleshooting

Explanation: AI-generated knowledge about Sophos Firewall captive portal bypass for authenticated users troubleshooting

Output:
According to the provided reference material [1], [2], [3], and [5], when troubleshooting a Sophos Firewall captive portal bypass for authenticated users, it is essential to understand the configuration and settings related to web authentication.

According to [1] and [3], the captive portal can be used to authenticate users through the browser when they try to access resources. However, this does not directly address bypassing the captive portal for authenticated users.

[4] states that the firewall rule that the traffic is matching must include the option 'Use web authentication for unknown users'. This implies that if the rule is set to use web authentication for unknown users, it may affect authenticated users as well, potentially causing a bypass.

However, [1] explicitly states that the captive portal is used to authenticate users accessing servers in the intranet zone if the user is not already authenticated with the firewall. This suggests that authenticated users are not affected by the captive portal authentication mechanism.

To bypass the captive portal for authenticated users, one possible approach could be to ensure that the authenticated users' traffic is not subject to the 'Use web authentication for unknown users' option. This might involve reviewing and adjusting the firewall rules to exclude authenticated users from this specific configuration.

However, without explicit documentation or additional information, it's challenging to provide a definitive solution for bypassing the captive portal for authenticated users. It's recommended to consult Sophos Firewall documentation, product support, or expert assistance for tailored guidance on this specific scenario.

In general, Sophos Firewall captive portal configurations and settings can be complex and nuanced. Any attempts to bypass or modify these settings should be done with caution and in accordance with the firewall's configuration and applicable security policies.
