Banking login URL page not found - Netgear ADSL & MikroTik

For some reason this banking web site does not work on two of the networks that I run:
http://www.sanpaolo.com/scriptIbve/vetrina/index.jsp

It’s a banking site that some of our customers use. Most of the page loads, but in the top right hand corner there is an Internet banking login section where you are able to enter a secure username / access key (with yellow buttons).

If tried it on both Internet Explorer and Firefox. The error is “the page cannot be found”.

Every other site I’ve accessed works 100%.

Do you use Netgear ADSL and MikroTik? Please can you tell me if this page loads properly (look at the top right for the access information buttons).
