Use policing or rate-limiting

If you are familiar with QOS on a Cisco router. If not, there are numerous articles available on the internet and I will be glad to help. Is your Windows 2003 server between the router and your LAN such that it is your default gateway for the LAN?

Windows NAT

by NetMan1958 In reply to CISCO 1801

I'm not sure how to configure NAT on a Windows server as I have never used a Windows server as a NAT device before. You will need to turn off NAT at the Windows server. In order for the router to do what you are wanting it will have to be able to identify which IP on the subnet.

Good Morning or Good Afternoon to your Tech guys - quick question please.
We are trying to set as an ISP to provide our clients (10 companies) within a small location with internet access. I have contacted a Telco company who provide us the service (Bandwidth) - we aim to buy DS3(45MB).

They have asked me of how many IP addressess do I require? And I am not sure what to say to them? Any ideas of volume of IP needed?

Please any help or pointer will do. Thanks,
