VPN only one-way (PIX-501)

Hello,
I'm setting up a PIX-501 as a VPN end point so that my internal LAN
resources can be accessed from the public internet. At present, outside
users can connect and be authenticated but can not map to shares on
internal servers. However, once the outside user has established the
VPN tunnel, inside LAN users can map to shares on the client's outside PC.
So, for example, an internal LAN user can "map x: \\\\192.168.4.1\\public"
and can see the files in that share. And, a LAN user can ping
192.168.4.1 and get proper responses. But the user at 192.168.4.1 can
not ping or map any shares within the LAN.
So, I guess I'm half way there. Or half-assed. Or something..
Here's my config:
