I should have mentioned that the above diagram depict the logical
interfaces inside the router. The router only physical connection
is via the bond to a switch stack, the logical separation of LAN and
WAN is done using VLANs.

The physical interfaces (eth0/1) are gigabit Ethernet, one FritzBox is
directly connected to the same switch, the second one is connected via
yet another switches as it is not in the same physical location. Like
this:

             (VLAN1)      (VLAN1)
             clients      clients
                |            |
             +-----+      +-----+
  Router <-->| SW1 |<---->| SW2 |
             +--+--+      +--+--+
                |            |
               FB1          FB2
             (VLAN2)      (VLAN3)
