Hi all,

Due to troubles with freeswan-2.04_1.4.8-12 I try to use
freeswan-1.99_0.9.34-80 (www.suse.de/~garloff/linux/FreeSWAN/).

What do I need to change in ipsec.conf to make it run?
I donn't understand the first error. What is wrong with my ipsec.conf?

If you need any more information, I'll be glad to provide it !!
Thanks in advance.
