[strongSwan] WG: problem connecting to juniper ssg5

Hello Jürgen,
it seems that the PSK is not the same on the Juniper
and strongSwan side. Therefore the first encrypted packet
cannot be decrypted correctly.
: "net-net" #1: byte 2 of ISAKMP Identification Payload must be zero,
but is not
: "net-net" #1: probable authentication failure (mismatch of preshared
secrets?): malformed payload in packet
Why do you define two PSKs for the same connection?
: loaded shared key for @lw.xxx.de @hq.xxx.de
: loaded shared key for @hq.xxx.de @lw.xxx.de
Regards
Andreas
