XG IPSEC Error - EST-P1: System did not accept any proposal received.

OliverKnights

Hello,

Hopefully some one can help me. I am trying to setup a IPSEC VPN connection with the Sophos XG firewall. I have configured the IPSEC policy for remote access and also the l2tp server. I have setup the Windows 10 Built in VPN client to connect to the firewall, but whenever i connect i get the following error logged in the firewall:

EST-P1: System did not accept any proposal received. Need to reconfigure the connection on either ends

Below is a screenshot of my IPSEC policy settings. 

I have tried to authenticate using a local user account and also an Active Directory one. Below is my Windows 10 Client settings

I am trying to use IPSEC with a shared secret

    Hi John,

    The error "EST-P1: System did not accept an proposal received" is basically stating that Phase 1 negotiations failed as as there was a mismatch in protocols.

    Check out the following knowledge base articles

    As you are using Windows Client I suspect you may not have removed the Kerberos authentication method and possibly not set up the pre shared key on the Windows side.
