idea about the source port scanning to destination

[mike <dmciscobgp () hotmail com>]

hello again
 
 
so was anyone willing to take on this idea? to refresh and ellaborate:
 
setting an option in nmap so that, as one scans a set of port ranges, the packet going out sets it's source port to 
match the destination. the reason i would like to se this added is simply that some services will silently drop a 
request not comming from the same number as the destination. i know of at least 2 services that do this. i beleive 
IPSEC is one and also RIP. i am sure there are others. why not have an option built-in where you are almost assured of 
a service response every time you scan? nmap is great and i feel it should take some pages out of the book of the 
UNICORNSCAN tool. that tool has revolutionized the art of port scanning and what can really be done (ARP poisoning on 
the fly scanning,etc). i know the project is failry dead/hardly ever updated and i know there will probably never be a 
windows port simply due to so many ip stack limitations 
 
someone look into this idea option and let me know if i should mention it again. still looks promising to me
 
than you
