Dlink DI-804HV to IPCop VPN connection

I needed more room in my home office so I downsized from an IPCop
firewall to a Dlink DI-804HV router w/ VPN capability. I have spent
most of two days trying to get the VPN link re-established between the
Dlink and a remote IPCop box at my company headquarters. I am amazed
that something so easy to do with Linux (IPCop) seems impossibly
complicated with the Dlink. No matter what I try, I cannot get the VPN
tunnel to establish between the Dlink and the remote IPCop box.

I am well versed in TCP/IP, setting up an IpCop firewall, etc, but my
VPN knowledge is very thin and I don't have time to become an expert
right now. Googling the web and usenet for hours has not helped
either. Help would be appreciated.

In a nutshell, here's what I would like to know: how do I transfer my
IPCop VPN settings over to the Dlink to establish a tunnel with a
remote IPCop box? In IPCop you use these parameters to set up a VPN
tunnel, and this is all you need:

Local Subnet IP
Local Subnet Mask
Local Subnet next hop (i.e., the local router)
Remote Subnet IP
Remote Subnet Mask
Remote Subnet next hop (i.e., the remote router)
UserName
Password

The Dlink, on the other hand, has many configuration parameters, some
of which resemble those above, and many others (encryption and
authorization algorithms, DH Groups, IKE proposals, IpSec Proposals,
etc etc.) which even the Dlink tech support folks could not explain to
me (yes, I've been on the phone with them for a couple of hours).

No matter how I try to configure the Dlink using my old IpCop
parameters, the VPN tunnel will not work. Sometimes the Dlink actually
lists an open VPN tunnel on its VPN Status page, but I cannot ping from
the local network to the remote one.

Has anyone done this before, or can you help in any way? Thanks very
much.

Alan
