Hi All,
I have a problem using SA with selectors based on <src IP>, <dest IP>
and <dst port> for outbound traffic.
I have written two out bound SA's for the same destination IP with
different destination port, but I am seeing
wrong SA has been selected for outbound traffic. My concern is why the
SA is not getting selected based on
ports mentioned security policy.
FYI..
content of file setkey.conf

*When a packet is sent to dest port 800 , SA which is getting selected
is 0x208[spi]

Please provide the criteria for outboud SA selection, please guide me
regarding this issue .
My Linux kernel version is 2.6.23.1-42.fc8
