Firewall
The Firewall is a router called firewall in the internal network. It makes sure all connections are routed through the vpn and switches (and later balances) traffic through our different Internet connections (Satelite, DSL, [planned Fiber, maybe LTE, Wifi]).
Configuration
We have at the moment a Debain running on a Z-Box (will be changed in the future). And configured the rules with “ferm”:http://ferm.foo-projects.org/.
At the moment the router switches at night to the satelite, to use the flatrate of the satelite between 0:00-6:00 UTC + 1.
