Ok, so I was on "another site" and they were talking way above me. I am technical inclined, but not a Cisco expert by any means.

I have a computer that sits behind a Pix 506 and Netopia router set on clearsailing with nat enabled on both. The computer inside all this has a route set in it so if I connect to a certain website it will redirect to an internal router that will then attempt to ping 1 of 4 predefined IP addresses on the web. If the router gets replies from the ping, it will then start a VPN to the "other side" and the information exchange to this website begins. If there is no response from the ping, the router goes into dial backup and communication is slooooow.

Here is a basic setup

PC  -
Supplied Cisco Router -  - I have no access to configure/change this device
Pix inside -
Pix outside -
Netopia Inside -
 Netopia Ouside -
I have been able to configure the PIX so my pings are getting a response and I stay out of dial backup. However, the PIX is blocking IPSec (or so I'm told) traffic so no data is moving back and forth.

From my understanding, I need to create a DMZ, an access list, and such, but I do not know how to do that. And as I search, I think I'm just confusing myself further.

If there is someone that could help me out. The commands for the PIX would be ideal

Thanks in advance for any help.
