tutorials say different things

[deathrider]

see we have this one http://blockland.us/portForward/

and this one http://forum.blockland.us/index.php?topic=35187.msg533436#msg533436

the second says the end port has to be 28030 but the other says no 30 so why are they different i was sitting here for ages thinking it only needs one port not a massive gaping hole
