Hello Noam, I may not have clarified myself. Basically, when I set wireshark to listen to sit1, it captures my ping6's Echo Request packets - but no replies.
I also found that there are no ppp0 or eth1 traffic corresponding to the ping6-created sit1 traffic (my PC has two Ethernet cards, and eth1 is the one which is connected to the ADSL modem; I use pptp and it creates the network device ppp0; in other words, any IPv6 traffic is supposed to pass through sit1->ppp0->eth1 and back). I did see ppp0 traffic when tspc creates a tunnel, and it indicates success in connecting to anon.freenet6.net (the IPv6 tunnel broker which I use, as it supports anonymous logins). After reading the "2008-08-25 - Configuring IPv6 using AARNet's free broker" article at http://www.nick-andrew.net/ I found that my iptables firewall blocked protocol 41 packets in both input and output.

The following iptables commands fixed the problem (where: IPTABLES="/sbin/iptables" INET_IFACE="ppp+"): $IPTABLES -A INPUT -p 41 -i $INET_IFACE -j ACCEPT $IPTABLES -A OUTPUT -p 41 -o $INET_IFACE -j ACCEPT --- Omer -- Did you shave a yak today?
