RB1200 as authentication, can't get access to the Internet

Hi there.
Never used one of these before but just installed one at a customer site who were already using one as an authentication system for wireless clients to Active directory by means of RADIUS.

Now, I went screen by screen copying the information form the existing MikroTik router and this one is in a new subnet and everything works with the exception that after the user has passesd authentication, their web browser can’t obtain a web page and the error is that Internet Explorer is unable to contact the server. DNS seems fine as from the workstation you can ping a http://www.google.com for example.

If I take the ethernet cable from the router that connects to the rest of the network and connect to a laptop and apply the IP address, subnet mask and default gateway I get Internet access fine. No proxy settings are used.

As stated earlier, their other router works fine. I’ve downloaded and applied the latest NPK file “routeros-powerpc-5.9.npk” but still no luck.

I’ve attached the latest config if anyone is able to take a look or suggest anything as I gone through every screen of the interface and can’t see anything wrong.

Many thanks for your time.

Cheers.
