[strongSwan] Strongswan and WP8.1

Tue Oct 28 11:38:38 CET 2014

Hi Andreas,

thanks for the feedback. The leftid is already set tot he FQDN of the server
"leftid=@FQDN of the server". I alo checked, if I had a typo error. The
server is reachable from the internet via the FQDN.

I just removed the FQDN in the logs I sent through the list.

Now the Lumia shows me the error 809, that the server didn't respond, but
there is a kind of communication between the lumia and strongswan:

10[ENC] generating IKE_SA_INIT response 0 [ SA KE No N(NATD_S_IP)
N(NATD_D_IP) N(MULT_AUTH) ]
