setting up PIX501 VPN

Dear All,

I am new to PIX and I have just recently purchased a PIX 501 and I am trying to get it to allow me to connect to my office network using the Cisco VPN Client.

At the office I have an ADSL line (dynamic IP). The modem connects to the PIX 501 (via cross over) and to the LAN port I have a small 4-port switch.

All clients from the internal network can connect to the Internet. I have used the VPN Wizard to setup the VPN connection (i have included configuration below). I try to connect via the Cisco VPN Client to the PIX from outside and not getting any reply from the VPN client.

Any suggestions?

A newly purchased PIX would have PIX 6.3(5), not 6.3(1), unless it was purchased used. If it -was- purchased used, then unless you happen to be in a few select EU countries (e.g., Germany, Denmark) then you don't have the legal right to use the software unless you "re-license" the device... in which case you would have upgraded the software. There are several security problems in

6.3(1) and 6.3(3), so you should be using at least 6.3(4).

The ip address pool that you use for vpn clients must not be the same subnet as your inside network. You could, for example, use but not anything in 192.168.1.x .

Your VPN Client configuration file would be helpful here. Since your DSl connection is dynamic, what IP address is your client set to connect to. Other helpful information would be found from your Client log window Log -> Log Window. Is the Client even able to communicate with the device?

Thanks for your message.

Although the connection is dynamic, the IP address hasn't changed.

Here it is the VPN CLient configuration:

[main] Description= Host= AuthType=1 GroupName=homevpn GroupPwd= enc_GroupPwd=92E1AC2A8AF298AE1EA6F3C210FC733B892515DF96553272A3B94A846A2F096397FA41E6AFB34B5E61DACBC62FCF73F8B164261645714F35 EnableISPConnect=0 ISPConnectType=0 ISPConnect=Tiscali ISPPhonebook=C:\\Documents and Settings\\tiago.lopes\\Application Data\\Microsoft\\Network\\Connections\\Pbk\\rasphone.pbk ISPCommand= Username= SaveUserPassword=0 UserPassword= enc_UserPassword= NTDomain= EnableBackup=0 BackupServer= EnableMSLogon=1 MSLogonType=0 EnableNat=1 TunnelingMode=0 TcpTunnelingPort=10000 CertStore=0 CertName= CertPath= CertSubjectName= CertSerialHash=00000000000000000000000000000000 SendCertChain=0 PeerTimeout=90 EnableLocalLAN=0

On the Log -> Log Windows nothing appears, and it doesn't seem that the Client is even "hitting" the PIX.

Any suggestions?

Forgot to change the log level - below if level 3 HIGH
