[Openswan Users] Problem with openswan RPM and FC4

[Nils Höres]

Hello list,
I got the following problem using OpenSwan Ipsec on Fedora Core 4.
I installed the following rpms : 
kernel-2.6.13-1.1532_FC4.i686.rpm
kernel-devel-2.6.13-1.1532_FC4.i686.rpm
openswan-klips-2.4.4-2.6.13_1.1532_FC4_1.i386.rpm

And whenever I start /etc/init.d/ipsec I get the following :
klips_info:ipsec_init: KLIPS startup, Openswan KLIPS IPsec stack version: 2.4.4
NET: Registered protocol family 15
klips_info:ipsec_alg_init: KLIPS alg v=0.8.1-0 (EALG_MAX=255, AALG_MAX=251)
klips_info:ipsec_alg_init: calling ipsec_alg_static_init()
ipsec_aes_init(alg_type=15 alg_id=12 name=aes): ret=0
klips_debug: experimental ipsec_alg_AES_MAC not registered [Ok] (auth_id=0)
ipsec_3des_init(alg_type=15 alg_id=3 name=3des): ret=0

Is this a known bug ? 
Are there any Kernel-OpenSwan combinations that run with KLIPS and Nat-t support out of the box ?
Thank you for any hints on this.

Mit freundlichen Grüßen / Kind Regards,
