Configuring Site-to-Site PPTP

I'm trying to configure a site-to-site pptp VPN using a Cisco 1700 and
804. I already have the configuration working on the 1700 as it is
currently providing pptp directly to PC's; however I also need to
allow the 804 (which is dialing directly into the 1700) to be a VPN
client.
I think the configuration (of the client (the 804)) should be
something like:
vpdn enable
vpdn-group 1
request-dialin
protocol pptp
initiate-to ip xxx.xxx.xxx.xxx
ppp authentication mschap
but I don't know how to get the tunnel to come up.
The 1700 is running NAT, the LAN is connected to Fa0/0 and current VPN
users come in and go out of Fa0/0 (they just get a local IP address)
the 804 will be dialing into the 1700, although it must be behind NAT
(Fa0/0 on the 1700 is outside, Bri0/0 is inside) essentially the VPN
on the 804 has to "reverse" the NAT, I need the systems on the E0 of
the 804 to appear as if they were directly connected to the Fa0/0
network on the 1700. Right now I'm using a second 1700 with a bridging
configuration on the second 1700 and the 804, but I need to return
that 1700 to regular service. Any help would be appreciated!

 

I was under the impression from a number of pages on Cisco's site and
usenet postings that you are able to do pptp site-to-site. If this is
incorrect how else might I be able to set this up?

Setup IPSEC tunnel bewteen the two...

 

Is there a site with good and clear instuctions on how to do this? I'm
very familiar with the IOS (pptp was a snap), but I get lost in the
key creation and so on that IPSEC requires. I don't need the data
encrypted over the VPN because it is a BRI, and don't neccecarily want
the overhead, but if that's the only way, I'll do it. I also do not
have the crypto module in this 1700.
