[Openswan Users] RHEL3 and new 2.4.21-32.EL kernel

[Mitja Sladovic]

Hi all,

Well, I have upgraded RHEL3 box on the latest 2.4.21-32.EL kernel. 
Openswan is 2.2.0.
But after upgrade I can't connect to other RHEL3 box with 2.4.21-27 
kernel (running openswan 2.2.0).

Somebody know what's changed in latest RHEL3 ipsec backport?

That's error:
