Is anyone else seeing a lot of 'strange' IPSEC traffic?
This mail server running FreeBSD did: (timestamps in CET, UTC+1) Nov 10 00:58:55 mailserver kernel: ipsec_common_input: no key association found for SA 77.174.253.13/77b40000/50 Nov 10 01:26:09 mailserver kernel: ipsec_common_input: no key association found for SA 77.174.253.13/03e80000/50 Nov 11 10:15:22 mailserver kernel: ipsec_common_input: no key association found for SA 77.174.253.13/62861b0e/50 Nov 11 14:35:34 mailserver kernel: ipsec_common_input: no key association found for SA 77.174.253.13/048b828c/50 Nov 13 20:00:53 mailserver kernel: ipsec_common_input: no key association found for SA 77.174.253.13/a5ff0000/50 I don't remember ever seeing these log messages before. -- Niels.
