I got a router and a http server in the same subnet. I need the server configures the router from within a CGI script.

The router uses CGI also (hardcoded). Simple http/form only works from local subnet as shown below:

<HTML>
<HEAD>
<TITLE>DI-604</TITLE>
<META HTTP-EQUIV=Content-Type CONTENT="text/html; charset=iso-8859-1">
<script language="JavaScript">
function SetTime(m){
	var f = document.getElementById("frmRule")
	var MinMilli = 1000 * 60
	var HrMilli = MinMilli * 60
	var DyMilli = HrMilli * 24
	var d = new Date()

    f.hour1.selectedIndex = d.getHours() % 12
    f.min1.selectedIndex = Math.floor(d.getMinutes() / 5)
    f.am1.selectedIndex = Math.floor(d.getHours() / 12)
    f.day1.selectedIndex = d.getDay()

	m = m + 4
	d.setTime(d.getTime() + MinMilli * m)

    f.hour2.selectedIndex = d.getHours() % 12
    f.min2.selectedIndex = Math.floor(d.getMinutes() / 5)
    f.am2.selectedIndex = Math.floor(d.getHours() / 12)
    f.day2.selectedIndex = d.getDay()
}
</script>
</HEAD>
<BODY BGCOLOR=#FFFFFF leftmargin="0" topmargin="0" onLoad="SetTime(60)">

</form>

Is there anything simple like a call to other CGI?

NPH- Proxy is the only way?

Found my answer here

#!/usr/bin/perl -w 

use strict;
use CGI::Carp qw(fatalsToBrowser);

use LWP::UserAgent;
use HTTP::Request;

my $url = "http://misitio.com/cgi-bin/datos.cgi";
my $query = "nombre=Uriel&apellido=Lizama&Edad=18";


my $ua = LWP::UserAgent->new;
$ua->agent("Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)");

my $req = HTTP::Request->new(POST => $url);
$req->content_type('application/x-www-form-urlencoded');
$req->content($query);

my $response = $ua->request($req);
my $content = $response->content(); #contenido de la respuesta

print "Content-type: text/html\n\n";
print $content;
