Hello,
I have besides the HE-IPv6-Tunnel a self-made 6in4-Tunnel for my own;
the host what is called POP is also operated be myself;
where would someone start to look for the problem ...
behind the ISPs router I have my own router; which has a RFC1918 IP on the WAN side,
and the ISPs router has the official IPv4 on its WAN-side;
e.g. on my router I see this on tcpdump
19:26:43.687781 IP RFC1918-IPv4 > POP-IPv4: IP6 prefix::1 > 2001:470:100::2: ICMP6, echo request, seq 18440, length 40
on the POP itself this:
19:26:43.720708 IP MY-PUBLIC-IPv4 > POP-IPv4: IP6 prefix::1 > 2001:470:100::2: ICMP6, echo request, seq 18463, length 40
19:26:43.720753 IP POP-IPv4 > MY-PUBLIC-IPv4: IP6 2001:470:100::2 > prefix::1: ICMP6, echo reply, seq 18463, length 40
as you can see, the packets go out of my router (my 6in4-gateway), through the ISPs router and my POP
and also back through the POP, but my router doesn't get them;
where is the probable mistake or can't I do anything?
Thanks,
Walter
p.s. the HE-Tunnel doesn't work either because of the same reason;
the reason of this strange behaviour:
the new modem had bugs in its firmware, which doesn't go conform with the requirements to let packets with protocol 41 untouched;
I got a new one which indeed was an old one, that doesn't touch the packets with protocol 41
