Well - the funny thing is that Firefox does not have that beheaviour - and
I don't know why. Could it be a portscanning-detection that activates ?
My firewall isn't very fast - but 533MHz CPU for a 6mBit line should IMHO
be fast enough ...

Hmm. Bad. I uploaded them to my Website.

Hmm. I could deactivate the ulog-d and let shorewall write to a file.
What exact directive should I give it to provide usable informations ?

Exact. But why does the system identify the packet not beeing part of a
generic communication ? The 3-Way handshak took place - and only std
requests get through after on... and I don't see a difference between
DNAT'ed packets and the DROP'ed packets ...

Thanks & Cheers
