I ended up figuring it out myself, after 2 more full days of trying more
things.
I got many suggestions, too many to list here, but they were mostly the
usual things that I already had checked and done, things such as checking on
the speed and duplex of the interface, contents of config files (many of
those), using lan_config, hwmgr, doing a complete network setup with sysman,
booting with genvmunix and many more...
At some point, I noticed that while looking at the logs, one of them was
growing a little and prompted me to check what it was, and there is was,
ipv4 packets were being dropped. This was in the auth log, where I would've
never thought ipsec or anything networking related would be logged there.
Actually, ipsec doesn't even identify itself in this auth log, I guessed it
was ipsec because of the packets being dropped.
What happened was that when I installed the system, I included the support
for ipv6 and ipsec for planned future use, so I wouldn't have to install it
later when I needed it. However if ipsec is actually enabled and not
configured, it will drop all packets, coming in or going out, silently, and
the only place where the evidence of this is in the auth log.
Let this be a lesson for the next guy like me who includes support for this
and forgets to either turn it off if not yet needed or to properly configure
it.
Thanks all for the numerous responses, I have a few other minor issues I'll
be posting about shortly..
