Problem setting up Firewall 1 / Cisco PIX site-to-site VPN

[SLECS99]

I am trying to set up a site-to-site VPN with a customer. I'm using Checkpoint 4.1 and they have a Cisco Pix.
We are using IKE, DES, and MD5 encryption, with pre-shared secret
When I try to remote desktop to the PC behind the Cisco Pix I see the following messages in my log viewer
Key install IKE Log Phase 1 completion DES/MD5/Pre shared secrets Negotation Id: xxxxxxxxxxxx xxxxxxxxx
Key Install IKE Log Received negotiation from peer: Negotiation ID xxxxxxx

I have several similar rules with other customers with Cisco Pix that are working.
Any ideas what the problem could be?
Thanks

What problem are you having? The messages that you have provided appear to be saying that you have negotiated Phase 1 but are not indicating a problem.

I'm expecting to see the phase 2 completion message for the subnets defined in my encryption rules. Since I'm not really getting an error, what could be causing this. Would it be that I'm not accessing the proper network (if they are NATing the network I am trying to get to). Would I get an error indicating this?
