Your gateway setting on your machine is correct at since that is the device that gives you access 'outside' of your office network. If I understand this correctly, the IC Share machine at your head office is the 'gateway' out to the Internet. But it doesn't sound like this machine is advertising this fact in any way so your inter-site routers do not know that this route to the outside world exists.
A way round it might be to add a static default gateway (default route) on the head office router to point to the IC Share machine

As far as I understand, the internet connection is given only to the IP address This might be your proxy server or a standalo ne PC with internet connection.

One work around is that you try & change your PC's internet browsers proxy IP address to with port setting 80 or 8080. If the internet connection is shared on that IC share PC then you will be able to browse internet from your PC after this setting change.
