How to limit traffic in Hyper-V?

Question

Hyper-V

There is a server with Hyper-V virtual servers based on Windows Server 2008 R2 Datacenter Edition. The server is located in a city where the Internet is very expensive.
There is an exchange point IX in this city (50-60 subnets).
It is necessary:
​​1. Organize the provision of Internet packages for access to networks outside IX.
2. Block access to networks outside IX if there is no internet package or when traffic ends.
3. Keep records of traffic in IX and outside IX separately.
The difficulty is that all this needs to be done on one server.
Are there solutions for such problems?
Thank you.

Answer 1

It's not entirely clear what side Hyper-V is here. Raise something like billing in a separate virtual machine, wrap all routing in it. Attach some ACLs to the virtual switch to protect yourself from cunning guys that manually correct the routing table on client virtual machines.
