Hi,

from time to time, with my IPv6 tunnel, I had random SSH connection drops (at least \
when idle), but did not find out what the culprit was. I've changed firewall \
settings, tunnel types, tried another server, added client keepalive settings, but to \
no avail.

Now I've discovered that it seems to be related to the IPv6 Privacy Extensions that \
assign a random IP every once in a while. When I have static IPv6 assigned via radvd, \
it works like a charm.

Is this a known issue? Is there a workaround?
Is it related to my iptables timeout configuration, or maybe a local problem on my \
(Mac) client?

The error message on the router always is "icmpv6_send: no reply to icmp error".

If anyone made similar experiences, let me know.

Thanks,
Florian
