Hay Franco,
we have Deutsche GigaNetz too and the same Problems as you describe.
I also found the solution to edit the GiF Settings MTU = 1492 and MSS = 1452 through Trial-and-Error.
Did you understand why we have to change the MTU and MSS to this specify values? Everything I read to the GiF topic says totally other values.
For me, it seems like the MTU is equals to the MTU of the WAN Interface and the MSS is the "real" MTU through the 4in6 tunnel.
