Making webpy framework accessible from outside the local network

I am using ubuntu 12.04.03. I have some basic experience with webpy and I had it working for my LAN just by following the tutorial. The framework needs to be able to be used from outside the local network. I have difficulty seeing how to make the framework accessible from outside the lan. I tried opening a specific port (with "# iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 8081 -j ACCEPT" then I check: "# netstat -ln | grep 8081 and I get: tcp 0 0 0.0.0.0:8081 0.0.0.0:* LISTEN" ) and use "python web_py_test.py MY_IP:8081" without success.

If I understand it at all, we can have a computer connected on a wifi with a non-static IP and there is a way to launch our webpy framework which can be accessible from the outside world. I am experimenting with the hello script:

Code:

import web

urls = (
    '/(.*)', 'hello'
)
app = web.application(urls, globals())

class hello:
    def GET(self, name):
        if not name:
            name = 'World'
        return 'Hello, ' + name + '!'

if __name__ == "__main__":
    app.run()
~

I observe that nothing is declared in the script about IPs or ports.

iptables-xml

IPTABLES-XML(8) 														   IPTABLES-XML(8)

NAME

       iptables-xml -- Convert iptables-save format to XML

SYNOPSIS

       iptables-xml [-c] [-v]

DESCRIPTION

       iptables-xml  is  used  to convert the output of iptables-save into an easily manipulatable XML format to STDOUT.  Use I/O-redirection pro-
       vided by your shell to write to a file.

       -c, --combine
	      combine consecutive rules with the same matches but different targets. iptables does not currently support more than one target  per
	      match,  so this simulates that by collecting the targets from consecutive iptables rules into one action tag, but only when the rule
	      matches are identical. Terminating actions like RETURN, DROP, ACCEPT and QUEUE are not combined with subsequent targets.

       -v, --verbose
	      Output xml comments containing the iptables line from which the XML is derived

       iptables-xml does a mechanistic conversion to a very expressive xml format; the only semantic considerations are for -g and -j  targets	in
       order to discriminate between <call> <goto> and <nane-of-target> as it helps xml processing scripts if they can tell the difference between
       a target like SNAT and another chain.

       Some sample output is:

       <iptables-rules>
	 <table name="mangle">
	   <chain name="PREROUTING" policy="ACCEPT" packet-count="63436" byte-count="7137573">
	     <rule>
	      <conditions>
	       <match>
		 <p>tcp</p>
	       </match>
	       <tcp>
		 <sport>8443</sport>
	       </tcp>
	      </conditions>
	      <actions>
	       <call>
		 <check_ip/>
	       </call>
	       <ACCEPT/>
	      </actions>
	     </rule>
	   </chain>
	 </table> </iptables-rules>

       Conversion from XML to iptables-save format may be done using the iptables.xslt script and xsltproc, or a custom program using  libxsltproc
       or similar; in this fashion:

       xsltproc iptables.xslt my-iptables.xml | iptables-restore
