issue with outbound SA selection

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
/************************* start setkey.conf ************************/
flush;
spdflush;

add 172.16.8.36 172.16.8.38[*800]* esp 0x201 -m tunnel -E 3des-cbc
0x7aeaca3f87d060a12f4a4487d5a5c3355920fae69a96c831
-A hmac-md5 0xc0291ff014dccdd03874d9e8e4cdf3e6;

add 172.16.8.38[500] 172.16.8.36 esp 0x301 -m tunnel -E 3des-cbc
0xf6ddb555acfd9d77b03ea3843f2653255afe8eb5573965df
-A hmac-md5 0x96358c90783bbfa3d7b196ceabe0536b;

add 172.16.8.36 172.16.8.38[*500] *esp 0x208 -m tunnel -E 3des-cbc
0x7aeaca3f87d060a12f4a4487d5a5c3355920fae69a96c831

# Security policies
spdadd 172.16.8.36 172.16.8.38[*800]* esp -P out ipsec
         esp/tunnel/172.16.8.36-172.16.8.38/require;

spdadd 172.16.8.38[*800] *172.16.8.36 esp  -P in ipsec
           esp/tunnel/172.16.8.38-172.16.8.36/require;
/************************* end setkey.conf ************************/

*When a packet is sent to dest port 800 , SA which is getting selected 
is  0x208[spi] 
with dstport 500 instead of 0x201[spi] **with dstport 800 instead**.*

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

Thanks and Regards
Naveen
