I am looking for some information on how to configure a site-to-site vpn connection using the pix 515 and the 1841 router. I have a remote site that I would like to connect to the corporate office via DSL modem. If anyone could give some assistance this would be very helpful.

Thanks; I need to give a little more information. The 1841 router will be located at the remote site with the DSL modem and the PIX is located at the corporate office. I am looking for some information on configuring the 1841 router for the remote site and configuring the PIX515 to accept the connection from the remote site.

does your remote 1841 have a static IP or dymanic PPPoE type IP.

if it is static IP the document I have sent you has the detailed steps in that. You can always some back for more help.

Implementing site to site VPN when the remote site is having a dynamic IP is also possible but the security would be weaker as it would dependent only on the pre-shared key.

try to convert your remote site to a DSL with static IP.

The remote site will have a static IP on the router. I haven't received the document yet.
