Internet Connection To An Existing NT Network

[BillAsl]

Hello All
I hope you can help as this is not my area at all. We have an NT based network, all have static IP addresses in the range 10.144.**.**, We have had installed by BT an ADSL connection for internet access and have been given a 217.41.**.** ip address range. BT have supplied a 5861 router and we have on our network already, Netgear 524 and 524S switches.
I am unsure as to how to route the internet onto our existing network SAFELY, could anyone help
Thanks in advance

Bill

Is your concern how to integrate this new router into your router farm, or how to firewall the internet?
