Hi Jon,

Here is my CDN$0.02..

I think that you will find that is how most of the consumer hardware
router/firewall devices work.  They should block unsolicited inbound
connections unless you have it configured otherwise.  This blocks a lot of
indirect attacks via open ports.   As has been pointed out locally it will
not protect you if you are using some sharing application that bypasses
the firewall (KaZa et. al.).    As an aside I found that my eldest was
running Morpheus on his Win95 system because it would hang the LinkSys
router.

With the LinkSys I believe that you can configure it to have a "trigger
port" that if activated with an outbound connection then the LinkSys would
automatically allow an inbound connection on another port (4200 in your
case).

Kind regards,

Mike

 >> That's interesting    as I have had the opposite experience (though I
admit  I may be missing something besides the CODE help system).

I don't understand firewalls etc. but they do seem to figure in the
picture
here.  When working from my home office via a DSL connection (and LinkSys
router) I can get autostart servers to work just fine.  STRCODE will not
work unless I open port 4200 on the firewall in the router.  I have made
the
assumption (which seems to be born out by experiments that I and others
have
made) that at least the LinkSys unit will allow inbound messages to a port
if that port (4200) initiated the conversation.  What it will not do is
accept incoming traffic on that port unless it is unlocked.

This has been my experience anyway - does it match yours?
