Hi list, 

since the update to 4.3 I have a problem with my IPSec configuration. I use it 
to secure my WLAN and it worked fine until the update. 

These are the ipsec.conf's: 

Notebook: 
ike esp from 10.0.1.100 to 0.0.0.0 peer 10.0.1.254
ike esp from 10.0.1.100 to 10.0.1.254 

AP: 
ike passive esp from 0.0.0.0/0 to 10.0.1.100 peer 10.0.1.100

The keys are where they have to be: 

Notebook: 
# ls /etc/isakmpd/pubkeys/ipv4
10.0.1.254

AP: 
# ls /etc/isakmpd/pubkeys/ipv4
10.0.1.100

First I thought it is a problem with my pf.conf, but I made a simple "pass all" 
with no effect. 

This is what the logfiles say: 

Notebook: 
isakmpd[28139]: rsa_sig_decode_hash: no public key found
isakmpd[28139]: dropped message from 10.0.1.254 port 500 due to notification 
type INVALID_ID_INFORMATION

AP: 
isakmpd[3588]: transport_send_messages: giving up on exchange peer-10.0.1.100, 
no response from peer 10.0.1.100:500

I searched for INVALID_ID_INFORMATION and found that the AP sends the wrong ID. 
But why? With little hope I forced both IKEs to use only IPV4, of course with 
no effect. 

So what am I doing wrong? Did something changed between 4.2 and 4.3 with IPSec 
and I didn't get it? BTW, unencrypted WLAN works fine. 

Thank you & best regards
