Sophos Connect: No response from gateway

Hi Bus709 

Thank you for reaching out to the Comunity! 

Is the UDP port 500 allowed by your ISP? If yes, do you see traffic from your public IP address on the XG firewall when you try to connect? 

Use the following KBA to run a packet capture on your public IP address and share the output:

Hi Ruka 

Please SSH into the firewall, and in the main menu, select option 4 and run the following command to check if there are any IKE packets from the client once you enable the connection. 

• tcpdump "port 500 or port 4500"
