Cisco VPN Client 2Wire Router Connects but cannot ping, browse directories

I am having difficulty accessing my work network from home through my 2Wire DSL Modem\Router supplied by AT&T.

Cisco VPN Client v. 4.8.01.0300
2Wire - Model 2701HG-B

The connection to the network "succeeds" but I am unable to ping anything on the network nor can I browse any file directories.

Is this symptomatic of a common problem with 2Wire routers?  My connection works elsewhere.

Thanks,  Chris

Do you get a private IP address, or a public IP address?
What do you connect to - a PIX FW? Is it configured to allow nat-traversal?

It is a private IP address: 10.10.x.x

Unfortunately, I am not sure if we connect to a PIX FW or not, and thus not sure if configured to all NAT-traversal.  I'll need to find that out.

Thanks, Chris

Check your client connection transport settings and see if you have enabled transparent tunneling and have UDP selected.
Try connecting with it un-checked.
Once you connect, open Status page and look at Route details.
What routes does it show as Secured Routes? Does this overlap at all with your local 10.10.x.x subnet?

I checked and transparent  tunneling is not enabled.

Secured routes include:
Network  Subnet Mask
10.10.10.0    255.255.255.0
10.10.100.0  255.255.255.0
10.10.110.0  255.255.255.0
10.10.200.0  255.255.255.0
10.10.250.0  255.255.255.0
10.20.0.0  255.255.0.0
10.30.0.0  255.255.0.0
10.40.0.0  255.255.0.0

No Local LAN Routes are listed.

The IP Address of the wireless router here at home is 172.16.x.x.

Thanks for your help so far,  Chris

Transparent tunneling not enabled on your client, or on the HQ side?
If it is not enabled on your client, then enable it by checking the box and then try again.
What kind of wireless router do you have? Do you have IPSEC Passthrough enabled on that router?

Sorry...transparent tunneling not enabled on my client.
Router/modem is 2Wire - Model 2701HG-B

I am having trouble locating an option to enable IPSEC Passthrough on the router...
