Hi Costa, thanks for your support and your product!
It is really essential for my life! :-)

And in this case?

Why it's matched and filtered?

This is the config with "router section"

=======
router ext2www inface eth1 outface ppp+ src "192.168.0.0/24"

       route all accept
=======

It's appears only occasionally with some clients and destinations
(including Google destination).

Thanks again

Regards
