Configure an IPSEC VPN connexion with OpenBSD (host to gateway)

Question

I'm trying to configure an IPsec VPN connexion with OpenBSD as a VPN Server with 3-DES for the Encryption, HMAC-SHA-1 for the Integrity, and PresharedKey for the Authentification.

My Questions are :

• If it's possible to do it with OpenBSD, can anybody give me a working tutorial to do this?
• If it's not possible to do it with OpenBSD, can anybody give me others solution and tutorials for this?
