 If I had hosted my mail and web servers at some web hotel this setup  - which does not include any tunnels – would be almost perfect and nothing more would be required.
-But I do have servers running at home. I realize that access to the servers is only possible via the fiber since the dongle is NATed – probable several times – so only outgoing connections are possible.

 In order to make the switch between connections seamless for the workstations (WS) and servers some means of setting the default route must be provided. Default routes are distributed by DHCP and are hard to chage after bootup. Enter the concept of Virtual Redundant Routers with the supporting protocol [[https://en.wikipedia.org/wiki/Virtual_Router_Redundancy_Protocol|VRRP]]. This gives the workstations and server a fixed default route while VRRP makes sure that there 'always' is an active router to carry the load.
