With both a 6to4 setup or a freenet6 tunnel I don't receive any reply to my packets.
I'm quite sure my firewall have the correct holes, but I even tried removing the firewall completely, just to be sure. Nothing. Tcpdump doesn't show anything coming from the tunnel or the ppp interface. I have exchanged few mails with the folks at freenet6 support and they saw my packets coming in, the replies going out, but none was reaching me. I'm now quite sure that my ISP is blocking incoming packets with protocol 41, it seems strange to me, but no other explanation comes to my mind... In June I had managed to use a 6to4 tunnel with the same ISP, so they must have changed something in these two months. Can you think of any other reason, apart from ISP problems, on why reply packets can't reach my interface ? Now I'll have to set up a modem PPP connection with another provider and additional costs, just to use IPv6. And I don't like it... My provider is Infostrada, one of the major providers in Italy, I'm using their ADSL service, if someone else is using that provider and ipv6, that would be great news for me. A question keeps biting be, though: why someone would want to block protocol 41 ? They aren't even offering IPv6 connectivity... -- ---------------------------------------- Daniele Venzano Web: http://digilander.iol.it/webvenza/
