is it possible to spoof ip behind NAT?

Question

hello!

is it possible to spoof the source ip if im behind a router that is using NAT?

if not, how do botnet programmers manage to make a SYN flood from their slaves? doesnt most of the home/business networks use NAT?

Answer 1

In short, No unless you have a leak in the protocol.

A botnet can still "do a SYN flood" but, in case where a NAT function delineates the corporate LAN from the Internet, it is the router that will get flooded.

Of course, the actual situation is more complicated than that but I won't get into fully describing it here.
