VPN tunnel a cisco 3640 with a sonicwall pro 230

[notShai]

i received these requirements from a company that needs a VPN tunnel to our site.
they use Sonicwall pro 230, we have cisco 3640.

i think this should be straight forward, but given the info the gave me i'm a little confused.

1. Based on the info below, what kind of a VPN are they requesting?
2. script sample / FAQ links would appreciated.

Here’s is what i got from them:
///////*******
IPSec Gateway Address = 62.xxx.xxx.xx
IPSec Mode = IKE Using Preshared Secret
Exchange = Main Mode
Phase 1 DH Group = Group 2
SA Life Time (Secs) = 28800
Phase 1 Encrypt/Auth = DES & MD5
Phase 2 Encrypt/Auth = Encrypt and Authenticate (ESP DES HMAC MD5)
Shared Secret = xxxsomesecretphrasexxx
Keep Alive = Enabled
Phase 2 DH Group = Group 1

We use a Sonicwall Pro 230, your Cisco 3640 will be slightly different in it's setup. you may need information/clarification on "translating your settings". We may need to play with the Encrypt/Auth settings to find a "compatible" pair.

The only information I'll need to setup the Tunnel completely is :

Your IPSec Gateway Name/Address (e.g. 81.159.264.151)
Destination Network & Subnet Mask (e.g. Network = 192.168.0.0 and Subnet = 255.255.0.0)
