You probably have a domestic home-router/firewall unit that does NAT. In
which case it will automatically open an outbound port when you send some
data unless you have put it into some overtly strict mode. For Windows
users it's nearly always better to use a program like ZoneAlarm's firewall
(and not the XP one) to detect strange outbound packets rather than having
too brutal a hardware firewall. The next thing to consider is if you always
initiate the connection or if the remote server tries to connect in. If
it's the later then unless the port is open it won't work.

Do exactly what it says in the setup instructions.

Do you know of another site?
Hey Harry, here's a damn fine suggestion. Why don't you tell us which
weather station and what software you are trying to use. Then we might be
able to give specific rather than generic advice. Or are we supposed to use
our individual Doris Stokes powers of ESP to figure out what you are
running because your current request reads like the following "I have a
piece of string, how long should it be?"
One final suggestion, download and install a copy TCPView. This was
originally a 3rd party program by SysInternals but they were bought by the
Borg and so it's a genuine Microsoft program now. Go to
http://technet.microsoft.com/en-us/sysinternals/default.aspx and it's on
the "Networking Utilities" page. If you run TCPView it will show you all
the UDP and TCP connections on your PC. Standby to find out you have some
stuff running and phoning home you'd rather not the 1st time you run it.
When it's running you should try and force a connection to cwop.aprs.net
and see if the connection is shown on TCPView. You'll at least know you are
hitting the server. You wont know if the server takes your data though. You
could run Wireshark to monitor packets going out and see the response.
Again it doesn't mean that you data is valid and being accepted but at
least you'd know the firewall was not a problem.
