Hi all,
just to give my two euro cents to our cause :)
Together with Maiko, I spend many many time
on run even impossible tests for a better understanding.
On my *specific* situation I found that one solution
found by Maiko and applied on the 2.0j.3 sources
is OK for my own running situation ... TNX Maiko!
However disabling my original setup and following the Mark
suggestion (see the last entry below obtained after an 'arp'
command) it appears with no effect here... the problem
remain unsolved :(

Naturally here there are no NATs, no firewalls, all is demilitarized and
so on.
May be, at this point, that the failure is caused by my SIEMENS / Made
in China
ADSL router ? Mine and other situations may belong upon this kinda problem.
