IPSec tunnel is UP and working correctly, logs show errors

EncapsICT

Hi there,

Today I ran into something I have not seen before, IPSec tunnel is up and working correctly. Log shows the following errors;

2 2020-10-12 13:54:36 info IKE [SA] : No proposal chosen
3 2020-10-12 13:54:36 info IKE [SA] : Tunnel [OfficeLAN_*****] Phase 1 proposal mismatch

26 2020-10-12 13:54:01 info IKE ISAKMP SA [] is disconnected

I usually encounter these errors when the algorithms are incorrect, in this case the tunnel does not come up. Today this log message pops up every few minutes while the tunnel is up and in use.

I have checked algorithm settings en local en peer ID-type/content.

Looking forward to a reply,

Kind regards, Niels

It seemed there was another VPN from a different location trying to connect to an inactive VPN gateway.
