nftables, vpn and bandwidth management.

Site A got 100 subnets [login to view URL] to [login to view URL] There is a linux router on Site A with the IP address .1 of any subnet connected to eth0:1 to eth0:100. There is one single internet connection provided by another router [login to view URL] which is connected to eth1 of the linux router ([login to view URL]).

The linux router on Site A should have a vpn connection to a linux router on Site B. All internet traffic from the Site A subnets needs to pass that vpn tunnel to Site B where it gets into the internet. The subnets are not allowed to access the other subnets except [login to view URL], where we got some services needed by all subnets.

You need to configure:

- the vpn tunnel (openvpn or something)

- firewall rules (nftables) that deny access between the subnets

- firewall rule (nftables) that allows access to [login to view URL] from any subnet

- routing all subnets internet traffic through the tunnel to the internet

- minimum (guaranteed) bandwidth for some of those subnets bi-directional (you must use upstream rules on routers on Site A and Site B for that)

- basic QoS rules (realtime traffic like VoIP first)

This is all theoretically! We want you to provide us the tools and commands we need to get it running.
