Thanks to Matthias Herzog for pointing me in the right direction. It seems that 2-3 months ago, AVM has released a new firmware for the Fritz!Box which does (non configurable) rate limiting on ICMP packets. The worst about this is, that they seem to be looking at the overall number of ICMP packets, not per sender or somethhing like this. By raising the ping interval in smokeping to 5 seconds, the problem went away ... cheers tobi

Email forwarding and backscatter, any idea how to solve?
by Benoit Panizzon 26 Apr '13

26 Apr '13

Hello World! I am working on renewing our ISP email solution. I'm focusing on minimizing any troubles while filtering spam etc. Eg, an email either arrives at the recipient or is rejected during SMTP handshake. Unfortunately some customers do forward their email addresses to other addresses, this can be internal or external addresses and this can be multiple addresses. In some cases it seems nearly impossible to me to prevent backscatter if you got email forwardings. How do other ISP solve that problem? Just tell you customers you won't offer email forwarding any more? Mit freundlichen Grüssen Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

We have this VDSL2 line at one of our customer sites, which aquired high packet loss from one day to the other ... we are using a fritzbox 7390 at the site and according to its log there are no problems, also the DSL Information tab does no count a high number of errors ... Here are the smokeping observations of the link http://oss.oetiker.ch/smokeping-demo/?displaymode=n;start=2013-01-15%2013:5… Any hints on getting this fixed. cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch tobi(a)oetiker.ch ++41 62 775 9902 / sb: -9900
