Moin,

i connected a OpenBSD/isakmpd and a FreeBSD/racoon router together
with IPSec and the tunnel is up know. But on the FreeBSD side I get
the following messages:

Jan 11 13:05:01 bullet /kernel: IPv4 ESP input: no key association found for spi 15572638
Jan 11 13:06:41 bullet /kernel: IPv4 ESP input: no key association found for spi 175788114

Jan 11 13:13:46 bullet /kernel: IPv4 ESP input: no key association found for spi 263880410

Was does this mean?

On the FreeBSD side I use the following setup
#!/bin/sh
setkey -FP
setkey -F
setkey -c << EOF
