You can change the first -> last range to anything you like, as long as you stay above 1024. The RFCs say to use 49152->65535, but some OSes use 1024->32768, some use 32768->65535, so anything you pick will be equally ok. :) Ignore the hifirst/hilast range, that's really only used by ftpd, it was a way to give ftpd a larger range of ports without changing first/last.
