I have a dynamic tunnel with an IPv6 network (Txxxx) and a static tunnel without a bounded network (Tyyyy). Now i got a little IPv4 network from my ISP, so i configured the static tunnel (Tyyyy) to my router at home, then i realized that i couldn't change the IPv6 network from the dynamic tunnelendpoint to the static one. So i deleted the static tunnel (Tyyyy) and tried to convert the dynamic (Txxxx) one into a static one, because the IPv6 networks are bound to their tunnel IDs. But after changing the tunneltype i get a message that the IPv4 address is already used und that PoP, although i've deleted(!) the other tunnel. Can anyone help me? cu markus
