Hi all,

i dont know if i am right but hope someone can help me.

System RB2011 6.48.6 .. Vigor Modem 130 for pppoE and a AVM Fritzbox (just for telephony).

As is am confronted for some while with following:

Mostly if i get an phone call or a Fax ..the Internetconnection is broken. And i dont know why ?!
In log i see peer is not responding .,..
i changed already back to the Telekom dynamic dns server cause i thought the cloudflare could be the issue. But the same behaviour.

What can i do to check and solve this error? I disconnected now the FB to see if it helps

thx for every hint

Regards
