Ipsec freebsd openbsd failure

[kasse]

Hello, I wanted to try and secure my wireless connection on my openbsd laptop via ipsec tunnel to my freebsd desktop. But I seem to get nowhere. So I tried to set up a more simple transport between the two to see if I could figure out what is wrong. But I still get the same errors. I have also tried between them as freebsd freebsd also no success. So here are the configs. I have disabled all the pf in this initial tests just to make sure that they are not the cause.

I want to try a ipsec transport from freebsd 192.168.0.100 to openbsd 192.168.0.103.

On freebsd I have compiled the kernel with ipsec and installed ipsec-tools.
Here is the racoon.conf

path include "/usr/local/etc/racoon";
path certificates "/usr/local/etc/racoon/certs";

As in http://="http://www.bsdguides.org/gu...ity/ipsec_vpn"
I do
isakmpd -Kdv and then when I try ipsecctl -f /etc/ipsec.conf
I get

ipsecctl: Syntax error in config file: ipsec rules not loaded

I cannot understand really what the error is

On the freebsd I run setkey -f /usr/local/etc/racoon/setkey.conf and
/usr/local/sbin/racoon -F -f /usr/local/etc/racoon/racoon.conf but when I look for loaded spd
with setkey -DP I get none. Also I get this same failure when I try freebsd to freebsd

[J65nko]

I tried you ipsec.conf on a 4.2 machine. I get the same syntax error. Only by removing the first two offending lines the two 'ike' rules load fine.

I am not an IPSEC expert. I once set up transport mode between OpenBSD boxes. When watching the traffic with OpenBSD's tcpdump I saw a lot of negotiation stuff.

Maybe you just should try it without those first two rules

Thanks!
I commented out those lines specifying the phase 1,2 crypto settings and set the freebsd to enc to aes. Now instead I get errors that there are no
configurations.
Now I have spd on freebsd

You have to use tcpdump with the -vv flag to see what is going on.
