Well, you can get this very error if you follow the steps I explained here: https://lists.debian.org/msgid-search/20160602225359.gb11...@cantor.unex.es If you provide a recipe to get that very error with firewall rules, I will believe that it may be firewall rules, but considering that most people do not block outgoing ping (most people do not block outgoing traffic at all), considering that we have a way to reproduce the exact error, and following Occam's razor, lack of capability is the most likely reason. Thanks.
