Precisely what you see depends on your software version, my current 
version is much improved over what I had before.  It sounds like what 
you had.

This guy says something ....

Mine are currently:
       Tx Power 56.0 dBmV
       Rx Power -5.2 dBmV
       Downstream SNR 31.3 dB Tx

Here is my lame perl script to grab this info if you can figure out 
what your problem with your firewall is:
=====================================================================
#!/usr/bin/perl

use strict;
use warnings;
use LWP::Simple;
my $url    = 'http://192.168.100.1/showModemRf';

my $html = get($url) or die "Couldn't get RF page";
$html =~ m{<TD>Tx Power</TD> \n<TD>([\d.]+)</TD>} || die;
my $tx_power = $1;
$html =~ m{<TD>Rx Power</TD> \n<TD>([-\d.]+)</TD>} || die;
my $rx_power = $1;
$html =~ m{<TD>Downstream SNR</TD> \n<TD>([\d.]+)</TD>} || die;
my $snr = $1;
print "TX Power is $tx_power dBmV\n";
print "RX Power is $rx_power dBmV\n";
print "Downstream SNR is $snr dB\n";
=====================================================================

I was just gonna rewrite this this morning to use rrdtools to make 
pretty plots, but since the original script no longer worked I got 
sidtracked.
