""can anyone give me some help in how i would configure a point to point ipsec tunnel?""

You mean how you would re-configure the existing tunnel?

It would help if we could look at the current configuration.

Telnet into the 2811, and log in (if required).

Type in this:
enable (enter)
show run (enter)

Please copy and paste the output into notepad, save the file and attach it to this Question.

BUT BE SURE TO:
- Edit all your WAN ip's to x.x.x.x
- Remove all your "ppp chap password 7 14521EF124" lines
- Remove all your "username xxxx password 7 14521EF124" lines
- Change the [key] to XYZ in this line in your config "crypto isakmp key [key] address x.x.x.x"

This is to keep sensitive information safe about your network.
