Hello Keyur,

Hello,

It is most likely due to not setting the Local ID. You can choose one of the available options in the drop down and then assign an appropriate value. To try, select IP Address for local ID and specify an IP Address there. Let us know how it goes after that.

Hello Ramesh,

according to documentation these fields are optional.

Best regards

Hello Petr,

You are probably getting a NO_PROPOSAL_CHOSEN because you may be having other IPsec connections defined with a similar setup (LOCAL_ID) not defined. In such situation it is possible that when the Client is initiating the IKE connection it is not matched against the Sophos Connect Client policy and instead matches one of the IPsec connection policy.

Please let me know.

Regards,
Ramesh
