Hi hope someone could help me. We've changed ISP and upgraded our DSL line from 512kbps to 2mbps, our new ISP gave us a username and password then I changed the account information on our Speedtouch 546 router. Now I could surf the internet only when I'm connected to the router directly. My problem now is the computer clients connected to my network could not browse the internet, server which gives them an error:
Forbidden you were denied access because: Access denied by access control policy

I could ping from webpages from client computers without any problem.

Can someone pls. tell me how to solve this issue. Thanks,
