Need assistance setting up a VPN tunnel

I have been given instructions on a VPN requirement for a vendor to implement an EDI system.

I'm running a untangle NG firewall with the following build:

Build: 9.4.2~svn20130830r35759release9.4-1lenny
Kernel: 2.6.26-2-untangle-686

Please forgive me because I'm about to betray my own ignorance in a big way.

The vendor has sent me the following list of requirements for the IPsec tunnel:

Here is how my setup currently looks in the rack app:

We have naught but a single subnet here (192.168.1.0/24)

I believe the devices on the other end of this tunnel are Cisco but the guy has been very conservative with what he's willing to tell me about it, offering instead to sell me a new appliance for these purposes if I'm not smart enough to figure it out.

The web admin IPsec gui seems rather threadbare but I'm sure this box is up to the task. I'm especially at a loss when it comes to creating the network interface objects and/or the static route. I'm also not sure how to meet his phase 1 and phase 2 requirements without laying eyes on a configuration page that makes explicit reference to those things.

I guess my question is: Is the unwired up to the task at hand here (I'm sure it is, but who knows) and how do I configure the more advanced requirements specifically and verifying the encryption phases?
