No bridging, no firewall, no complex routing: the IPSec gate Fhave
only one default gateway.

[root@R2]~# sysctl -a net.inet.ip.fastforwarding
net.inet.ip.fastforwarding: 1

I didn't understand why you ask me the status of the fastforwarding:
Then I've disabled it, and re-try my IPsec configuration=85 Problem
solved !
I've found the notice regarding fastforwarding being not compatible
with IPSec in the inet(4) man page: I was not aware of this
compatibility issue.
I've proposed a little improvement on the rc.d/ipsec script for
checking the fastforwarding state : PR/183303.

Thanks a lot's Yvan !!
