I've done my very best to replicate both your data and your regexs as you supplied them and all the regexes, including the one I gave you appear to match every line of data.

My results

Which leaves me at a loss to explain your findings?

My test script 

#! perl -sw

my $re_ip = qr/(\d+\.\d+\.\d+\.\d+):\d+/;

my @re_lines = (
    qr/ ^ \s* $re_ip \s* -> \s* $re_ip \s* -> \s* $re_ip /x,
    qr/^\s*$re_ip\s*->\s*$re_ip\s*->\s*$re_ip/,
    qr/^ \s* $re_ip\s*->\s*$re_ip\s*->\s*$re_ip/x,
    qr/^\s*$re_ip\s*-> \s* $re_ip\s*-> \s* $re_ip/x,

    qr/ ^ \s* $re_ip\s*->\s*$re_ip \s*->\s*$re_ip/x,
);

while (my $line = <DATA>) {
    print $line;
    for my $regex (@re_lines){
        $line =~ $regex
        ? print ' Matched!'
        : print ' No match!';
    }
    print $/,$/;

Okay you lot, get your wings on the left, halos on the right. It's one size fits all, and "No!", you can't have a different color.
Pick up your cloud down the end and "Yes" if you get allocated a grey one they are a bit damp under foot, but someone has to get them.
Get used to the wings fast cos its an 8 hour day...unless the Govenor calls for a cyclone or hurricane, in which case 16 hour shifts are mandatory.
Just be grateful that you arrived just as the tornado season finished. Them buggers are real work.
