Please help. I have used VPN wizard to configure PIX 501. When testing with 3.6 client I have no traffic between client and internal network. Looks like I have tunnel open and client have address assigned from the internal pool. Configuration and Debug output is listed below.
Thank you,
AJ

Try removing this line via the CLI:
> no crypto dynamic-map outside_dyn_map 20 match address outside_cryptomap_dyn_20
Also, you have this:
> ip local pool Sackett 10.0.1.16-10.0.1.25
> dhcpd address 10.0.1.8-10.0.1.135 inside
So your VPN client pool and your DHCP client pool overlap, this is not good, so change that too.

I have made all changes and still no go. I have attached changed configuration and show crypto outputs.
Thank you for your time,
Andrew J.

Andrew,
Based upon the "Show crypto ipsec sa", looks like you are able to successfully make a IPSEC Connection from the VPN Client to the Pix 501 but not able to pass traffic.
If 68.72.174.119 was the Public IP Address of the client, I see Decrypts on the IPSEC SA and but Encrypts. This basically means, the Pix 501 is receiving traffic from the client but is not able to send it back for some reason.
1. After successfully connecting to the Pix501 with the VPN Client, What IP Address did you try to access.
2. Does the IP Address know how to get back to the Pix501.
3. Also, do a clear xlate and see if that makes a difference.
I hope it helps.
Regards,
Arul

AJ, It looks as though your IKE Phase 1 (shared key exchange) is not completing. It is trying 9 times and fails. Your transform sets show ESP-DES-MD5. Are your clients doing this also? I think they may be trying to connect at 3DES instead or another Diffie-Hellman Group (1 or 5). This appears to be a simple mismatch of settings. Let me know via email if you wish.

Im using Cisco VPN client 3.6. I was thinking it supports all required protocols. Is it true ?
Thanks,
AJ

ajachowicz,
Did you ever resolve this problem?
I've run into a very similar situation and was wondering if you'd come up with a working solution.
Thanks!

No it the version you may using may not support the same combination of phase 1 security policy.
Upgrade to latest version. However, to do a simple test add another policy with lower security and try again. If this works than you current version does not support the SA phase 1 you set.
Let me know if this works,
08-11-2006 10:00 AM
try these policies for example,
isakmp policy 10 authentication pre-share
isakmp policy 10 encryption 3des
isakmp policy 10 hash md5
isakmp policy 10 group 2
isakmp policy 10 lifetime 86400
isakmp policy 20 authentication pre-share
isakmp policy 20 encryption des
isakmp policy 20 hash sha
isakmp policy 20 group 1
isakmp policy 20 lifetime 28800
let me know if works,
