Make sure the following lines are not repeated in your 90adjustTransProxy
if (defined $squid{BypassProxyFrom})
{
my $bypassproxyfrom = $squid{BypassProxyFrom};
foreach my $bypasssource (split(',', $bypassproxyfrom))
{
$OUT .= " /sbin/iptables --table nat --append $pf_chain\\\n";
$OUT .= " --source $bypasssource --jump RETURN\n";
}
}
If repeated, just comment them out!
