[strongSwan] Problem: strongswan 5.4 with sha2

[fatcharly at gmx.de]

Hi,

I´m using a strongswan-5.4.0-2.el7.x86_64 on a CentOS 7. I´m trying to build a VPN connection with the following proposals: 
ike: RSA, DH20, AES256/SHA-2
esp: DH-14, AES256/SHA-2

I`ve tried it with this:
ike=aes256-sha256-ecp384
esp=aes256-sha256-modp2048

but its not working. WHich would be the right setting for this ?

Any suggestions are welcome.

Kind regards

fatcharly
