Dear all,

I'm new to openswan and I'm trying to configure it. I got the following
information from the gateway I have to open an IPSec tunnel with:

Authentication Method : Pre-Shared Secret
Encryption Schema IKE
Perfect Forward Secrecy-IKE : Diffie-Hellman Group 2
Encryption Algorithm: AES128
Hashing Algorith: SHA-1/MD5
Renegotiation of IKE SA : 86400 seconds

IPSec : ESP
Perfect Forward Secrecy-IPSEC: Diffie-Hellman Group 2
Encryption Algorithm: AES128/3DES
Hashing Algorithm IPSec: SHA-1/MD5
Renegotiation of IPSec SA: 3600 seconds

My /etc/ipsec.conf looks like this


version	2.0	# conforms to second version of ipsec.conf specification

# basic configuration
config setup
	# Debug-logging controls:  "none" for (almost) none, "all" for lots.
	# klipsdebug=all
	# plutodebug=dns


# Add connections here.

# sample VPN connection
	conn sample
# Left security gateway, subnet behind it, next hop toward right.
	left=x.x.x.x
	leftnexthop=%defaultroute
# Right security gateway, subnet behind it, next hop toward left.
	right=y.y.y.y
	rightnexthop=%defaultroute

        ike=aes128-md5;aes128-sha1
        esp=aes128-sha1;aes128-md5;3des-sha1;3des-md5
        ikelifetime=1d
        keylife=1h
# To authorize this connection, but not actually start it, at startup,

	auto=start

conn block
    auto=ignore
conn private
    auto=ignore
conn private-or-clear
    auto=ignore
conn clear-or-private
    auto=ignore
conn clear
    auto=ignore
conn packetdefault
    auto=ignore

Is there something wrong or something missing in this configuration file
according to the details that I got ?

Thanks a lot
