Hi sorry to crosspost this to two mailinglists. I get this error on both StrongSwan 2.2.0 and OpenSwan 2.1.5 on a vanilla kernel 2.6.8.1 box (Slackware 9.1): ignoring Delete SA payload: PROTO_IPSEC_ESP SA(0x25d1db74) not found (maybe expired) I get ping trough any tunnel but no other traffic. Thanks for any help Philipp
