VPN between Cisco 1760 and StrongSwan

[radian7]

Hi

I try to make tunnel IPSec between Cisco 1760 and StrongSwan
witj following parameters:
hash function for phase I: md5
encyption funcion for phase I: 3des
Diffie Hellman group for phase I: PFS2
LifeTime for phase I: 7200sec
hash function for phase II: md5
encyption funcion for phase II: 3des
Diffie Hellman group for phase II: PFS2
LifeTime for phase II: 7200sec

Unfortunately it fail in phase one.
