Traffic monitoring in small office
In my office, we have 11 computers. We have 2 2M broad band accounts from our ISP. We use a router combines 2 income cable and use 2 8 ports switches to make every computer have the Internet access. The problem is right now we got very unstable Internet access. Therefore, I'm thinking of instead of directly connect 2 switches to router, I connect 1 Debian box(has 2 NIC) to the router and then distribute the Internet access to all 11 PCs through a 16 port switch which is connected to the Debian system. In this way I can install traffic monitoring application s on Debian box to analyze the problems. Can any of you tell me whether this is a good way to do it please? If it is what are the applications I should put in Debian box? If it is not a good way, what is your suggestions please?
Thanks a lot！
