high packet loss without exposed host
« on: May 01, 2015, 09:41:12 AM »

I tried using a tunnel to a local Banana Pi running Lubuntu 14.04. The Banana Pi is connected to a DSL router (Vodafone EasyBox 802 with newest firmware 20.02.235) which gets dynamic IP addresses. Currently I have set the correct address manually, but this is only for testing purposes to reduce the number of possible failures.

When I run "traceroute6 -w 2 -q 10 ipv6.google.com" (results see bolow) or ping6 I see quite a high number of packet losses and the connection does not seem to work reliably. If I configure the Banana Pi as exposed host ("DMZ") in the router everything seems to work correctly, but I don't want to use that configuration.

Other settings in my router are only port forwarding for UDP or TCP ports and I could not find any information if it supports protocol 41.

Is there anything else I can do or do I need another tunnel broker which supports AYIA (e.g.) to use a UDP port which should work over NAT?




Her is the output of traceroute:
