We have users using cisco client VPN to connect to our PIX 506E

By default the Cisco client is configured to not allow "Split-tunneling". This isolates your local network from the VPN, and therefore the corporate network, as an important security feature. As a result it also blocks your local access to the Internet.
Split-tunneling can be enabled, but it has to be done by on the PIX, by the Cisco administrator. It is not recommended.
If you are the admin and looking for the commands somebody else will be along to assist. I am not a "Cisco guy".

Hang tight, I'm sure someone will be around. It's fairly straight forward, but I don't have a grasp of the commands, and some differ with different OS's.

If this is the only VPN that the pix has on it, then you can use the ACL that is configured for the nat (inside) 0 command to configure the split tunneling.


vpngroup xxxxxxx split-tunnel   access-listnamenumberfromnat0

or if you have multiple vpns and only the split tunnel for this specific group, create an acl
!
access-list splittun permit ip x.x.x.x 255.255.255.0  z.z.z.z 255.255.255.0
!
replace x.x.x.x with your internal subnets, and z.z.z.z with your ip pool addresses (adjust mask lengths to be the correct ones :)  )  add multiple lines for multiple inside subnets.  Then:
!
vpngroup xxxxx split-tunnel splittun
!
hope that helps!
