Still no internet

I have a weird problem! I am in an office block that shares a connection via a managed router. It turns out that the previous tenants had a server in the building and strange IT set-up. Now the ports that they used to use will not work with the managed router's DHCP set-up.
As a result, still no internet at the office besides a mobile broadband set-up via a mobile phone and my laptop.
This means that the office machines are not clocking up many hours per day and the BOINC contribution is way lower than it normally would be. I am hoping t get this sorted out with the QLD based ISP today ....

EDIT: 16:15 and they have sorted the problem out! A night of crunching ahead for the "farm" :-)
