well, a reboot, changing runlevels or at least a "telinit q" is
necessary to make init aware of the changed inittab. I didn't mention
this before...

OK, then it worked. But please note that the "s0" is the name of the
inittab entry (read "man inittab") and doesn't per se specificate a
device. That's done in another place and the correct device name is
ttyS0 (capital "S"). The line could have a totally different name.

Anyway, the inittab issue seems to be gone for you, that was just a
clarification. All that seem to be left is your firewall problem
(doesn't seem to be embedded-specific, so you might want to ask on
-security or -user).

Sorry, I can't help here as I'm not using any firewall builders. But
you should disable lines that e.g. specify that only certain
applications are allowed to access the net (that would probably be
command matching).

As a side note: You *did* compile full netfilter support into your
kernel, didn't you?
