I see exactly the same effect with GRE packets that make it out
the default masq'd interface before the correct route for them
is established. When the correct route comes up, the packets go
there but continue to be source-NATed with the address of the
incorrect masq-ing interface. It appears to be impossible to ever
change a route after an ip_conntrack entry has been established, at
least when NAT is involved. Is there a better source for information
about the ip_conntrack module than this list?
