Yes, sorry about the clutter in my message.

Not certain.

2/ how many times?
at least twice. Its well possible that earlier cases were masked by
reboots from other reasons. And it has taken me some time before i
linked particular slow network behaviour to a firewall problem
3/ how stable is the 1 month gestation time?
no certainty on this one.
OK, problem is back. About 3 days more then 1 month.
IPv4 browsing is very slow, IPv6 routing is down. I can no longer ping6
ipv6.google.com. It gets the AAAA record, but no responses. Not even
when doing it on the firewall itself.

"ip -f inet6 route flush" makes no difference. Neither flushing the
neighbor cache
ifdown / ifup of the external ethernet port makes no difference
"rmmod tg3" removed both interfaces (so the driver does indeed handle
those ports) followed by "modprobe tg3" made no difference either.
package firmware-linux-nonfree is current.
stopping aiccu, rmmod sit and tunnel4 and then reloading and restarting
aiccu did solve it
Next time i will start with restarting aiccu, and not rmmoding the
related modules
Cheers,
Rudy
