Cisco PIX 501 to Cisco Concentrator 3005 via Remote Access

Answered Question
Feb 6th, 2007

Hello folks,

I need your help.

We got a Cisco PIX 501 in one location and this pix is configured for pppoe dial out. The pix connects itself to the internet via pppoe client. ping to an offical ip is running well.

So what I want to do is to establish a von tunnel between this pix and a cisco 3005 concentrator.

But I was not successull to establish it.

Here is the pix config. the acl?s are only for testing and will be replaced if it works.

PIX Version 6.3(4)

vpnclient server 212.xx.xx.xx

vpnclient username pixtest password ********

terminal width 80

on the concentrator I created a user pixtest, a group vpntest and I?ve created rules for the network e.g. to which server the users behind the pix will be able to access.

And that?s all.

I could not send you the output either of the pix or concentrator because I did not get an error or a message that the tunnel will be established.

What can be wrong ?

Thanks for the replies

I have this problem too.

You are missing the command "vpnclient enable" on the PIX.

This sample configuration demonstrates how to form an IPsec tunnel from a PC that runs the Cisco VPN Client (4.x and later) to a Cisco VPN 3000 Concentrator to enable the user to securely access the network inside the VPN Concentrator.
