Problems with VPN settings using Pix firewall and VPN clients with preshare

I am trying to configure a virtual private network using a PIX firewall with version 6.1(2) and VPN client version 1.1.

The actual PIX configuration was done using access-list acl_in and access-list acl_out commands and their respective access-group acl_in and access-group acl_out applied to the interfaces where the rule is effective.

Everything works OK with this, but now I need to implement the VPN configuration to receive remote dial-up VPN clients. I am using exactly the configuration that appears at the Configuring PIX-to-VPN Client Wild-card, Pre-shared, No Mode-Config example and it does not work. I am not able to pass traffic across the tunnel, but it seems as if it´s open. While performing debugs it seems that there are no errors with phase 1 and 2 authentication. Also, it appears that I get the IP of my access-list pool address. Could it be a problem with the other access-lists (acl_in and acl_out) that I am using for the other purposes?

What could it be the solution? I have implemented the same using the same VPN client 1.1 but pIx firewall version 5.1 and with conduits instead of access-lists and worked immediatly.

Any suggestion?
