PPPoE connection on XGS 2100 SFOS 19.0.0 GA-Build31 - slow page loading

Hi Carlo

Can you place an unmanaged switch between the PPPoE modem router and Sophos XG?

Regards 

When I turn off DNS service browsing speed on clients improves on clients

but firewall is not connected to sophos central behind pppoe connection with or without dns service running when using pppoe connection.

Please show us your DNS settings

Hi Carlo 

Please select DNS query configuration as Choose server based on incoming requests record type and click on Apply and share the Test name lookup output for utm.cloud.sophos.com,community.sophos.com, google.com

Thanks and Regards

Hi Bharat,

the screenshot was from my sophos not Carlo's one

Thank you. We tried all possible combinations for DNS through GUI but nothing seems to work. 

I need support from Sophos and ISP for this one.

In the end, it is easy to find out, who is responsible for this issue.

Simply do a BPF string in Packet Capture on Diagnostic - Webadmin with: port 53 

Then filter for your PPPoE Interface.

If you see packets leaving the interface with the correct IP to the internet (DNS Server), the ISP is responsible for this issue. 

Can you please share correct syntax
