Hello,

slowly I become mad:

Thus:

I have a SMC 7004ABR V2 and behind it a SWITCH for my PCs and the Fritz box.

__________________________ |-->Fritz box --> Telephones
| DSL fragment/modem --> SMC |
__________________________ |-->SWITCH for PCs

Thus I can reach the Fritz box via the SMC (192.168.2.101). It light, as if also outgoing discussions would function (had a ringing tone), but arrive detailed nothing.

Property in the SMC the following of haven de-energised (are with 1&1)
1und1 FAQ:
5070 5072 3478 30000-30005
and at other one place heist it: 5070 - 5079 and 30000-30019

With the Fritz box (I hope in such a way) everything is like that as it to be is: DSL via LAN A, no DHCP. Fritz box refers even automatically a IP address of the SMC.

No discussions come purely nevertheless, who calls gets only “briefly” occupied. Normally put in the whole functions immediately.

Who can help? I view the no more…

I looked for, also much here found however not the correct reference…

Thanks
