Interface problem

hi there ,

i have one public interface: xxx.xxx.79.43

and

one internal interface: 192.168.0.1

i added another network card to the server on the

internal lan with 10.10.0.1

-The problem is that from 10.10.0.2 (my pc)

-i can’t ping other hosts on 192.168.0.0/24

-i can ping yahoo site

-i can ping 192.168.0.1 and 10.10.0.1

-i can ping the D.G xxx.xxx.79.41

-i get dns error when i try to open sites.

-i can’t browse internet sites

-msn and yahoo messngers works fine.

i use transparent proxy ,
i gave 10.10.0.2 the suitable access and the cache rules inside webproxy rules.
-Am i missing some thing here or not?
