Routing LAN traffic to another IP

In our office we have a LAN setup which is firewalled but a single system has an open IP, meaning there are no restrictions with respect to browsing. Youtube, Facebook, Twitter opens without any firewall filtering and all other systems connected to the LAN network has restrictions. How do i configure both the systems so that i can route my LAN (Internet) traffic to the system which has no restrictions so that i can also browse youtube, facebook etc.

My IP - 10.5.12.107
Subnet - 255.255.240.0
Gateway - 10.5.0.1

Open IP - 10.5.13.58
Subnet - 255.255.240.0
Gateway - 10.5.0.1

P.S - We don't have any serious security policies in place which says i would be punished if i use facebook or youtube :)

Ummm.....I didn't see this thread for long time....but since this went un-answered so dropping by a solution.

A very simple an easy way to achieve this would be to setup a proxy server on the machine without any restrictions, and setup your gateway as that proxy server. That machine will do the internet traffic transactions on your behalf and to the firewall, it will appear that it's the Open machine which is sending the traffic and not you, unless both machines are directly connected to the firewall.

The other way around is only possible when the un-restricted machine isn't on the network as active device. You can simply mask it's IP address and use it as your own, if you both are in the same subnet. This is basically spoofing of IP address. Based on the IP schema you have shared, it looks like they maybe in the same subnet. However, this is not legal :\. Spoofing is not good.

Thanks for answering Hrishi. Could you explain me a little more in detail. Say, software recommendation for setting up a proxy server (w/o any restriction) and yes, both the machines are not directly connected to the firewall.
