Functioning IPsec VPN, EST-P1 error on both sides

Jeremy Hunt

I have a functioning VPN between a XG210 and a XG85, yet both sides are spitting out the following error:

 

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

 

Can someone explain to me what steps I should take to resolve this?

    Thanks, Keyur.

     

    The site-to-site connection is active and connected. Earlier, I inactivated it and reactivated it and the VPN connected up with no problem, but I still got this error.

     

    In looking at the configuration of both, they seem to be identical (Aside from each having distinct endpoints and network details). The remote site is setup as the initiator and our home site is set to respond only.

    Hi  

    If the communication working flawless, I suspect that it may be because we have select multiple SPI while configuration and maybe one of them may be mismatching while negotiation. It would be great if you could provide more logs, It might be possible it is from different IPsec VPN tunnel which is configured and active but not used.
