How do I setup IPsec VPV connection between Sophos XG and Cisco ASA? I have created the connection but not working. What could be the problem?

Hello, could you provide a configuration from both device?

The original poster did not give us much to work with. So a request to see configurations is a good place to start. The original poster asked what could cause the problem. Here are some of the things that I would check:

- is there successful IP connectivity between your peer address of the vpn and the remote peer IP address (can both sides ping the peer IP address, specifying your own peer IP address as the source)

- is the crypto map configured appropriately and is it assigned to the correct outgoing interface?

- are you sure that you are routing traffic to the remote peer out the correct interface?

- if the ASA is doing any nat, is there an identity nat/nat exemption configured for the vpn traffic?
