if you have the file content in an array, you could try something like:

my @sorted = 
  map  { $_->[4] }
  sort { $a->[0] <=> $b->[0]
                  or
         $a->[1] <=> $b->[1]
                  or
         $a->[2] <=> $b->[2]
                  or
         $a->[3] <=> $b->[3] }
  map  {
    if( my (@ipParts) = $_ =~
          m/dst outside:(\d+)\.(\d+)\.(\d+)\.(\d+)/ ) {
      [ @ipParts, $_ ]
    } else {
      # what shell I do if pattern not found? use 0.0.0.0?
      [ 0, 0, 0, 0, $_ ];
    } # else
  } @input;

Perhaps you have to change the pattern match...
