Remote VPN setup through PIX (Please help)

Unanswered Question
Oct 24th, 2007

I'll try this one more time and try to be as specific as possible. I am an intern at a small consulting firm. Our network is very basic, ADSL modem to PIX 501 to switch. We have a web and FTP server onsite and about 5 client workstations. We need to be able to VPN into the network for a couple of reasons. 1. We need to access SQL server remotely, which is stored on our server. 2. We have an IP telephony system that we would like our remote employees to be able to use. The VPN client we will be using will be CISCO VPN Client version 4 and up. I am a network intern, (the only network guy here) and have a basic knowledge of VPN's and CISCO products. I can somewhat maneuver my way around the IOS. For some reason when I try to access the PDM, it never loads. So here is my cry for help. I would really appreciate some help. If you need me to post config files, please let me know. I have found a lot of documentation on the internet, but because our PIX is already up and running, I don't want to change anything unless I know for sure it won't mess anything up. Thanks in advance for any help you can give.


I have this problem too.

That should get you pretty close. There are more options not listed and some things you may want to change, groupname, vpn pool addresses etc.

I'll definitley try this. Thank-you very much. One more question: I typed the vpdn command on the ios and it says i have an active session up. The remote mac address belongs to our ADSL modem. Is this normal to have a VPN tunnel from your modem to the PIX?

vpdn has nothing to do with your vpn. This is typically used for PPPOE to your isp.
