Newbie VPN Question - Part Two

Hello,

Thanks for all the input I've received so far.

After my last post, I did config factory-default, wr m, and reload. I then re-configured based on input received from Mr. Roberson here.

My intentions are as follows for my PIX501:

Allow 9 individuals VPN accessability (L2TP) from their homes to the internal network via cable modem.

Home -> Cable Modem -> Internet -> Work DSL -> Pix501 -> Work Server

I have configured the PIX via the PDM GUI's VPN Wizard to test one of the users as noted in the config file below. The individuals' home computer is WinXP. I have configured a new L2TP VPN connection via the internet on the home computer.

I have the following questions on the config file I've posted.

  1. Access-list inside crypto-map lists 10.0.10.16 255.255.255.240. Why? Gateway is 10.0.0.1 255.255.0.0. Same with access list outside?

  1. PDM location is the same IP and Subnet Mask as #1 above. Why?

  2. Does the confuguration seem resonable based on what I want to accomplish?

When I tried to connect to the office via the home computer, no luck. Received an error 678 Not responding. I can successfully ping the static IP address assigned to the outside IP address of the PIX.

Firewalls are off at home during this test. Computer connected directly to cable modem at home during test.

Any input to help me get on the right track would be appreciated.

I can post the Win VPN connection properties if needed.

PIX501 config follows: I have intentionally double spaced after any line wrap.
