Yes, that is indeed what the man page says and it is the expected
behavior. You've reported here, however, "Currently,  the peer can set
any IP, for example 10.1.0.4, and can send packets to my
http://10.1.0.1:80 from 10.1.0.4," which sounds bad and like something
worth taking seriously, if I'm interpreting that correctly. Would you
take the time to create a reproducer similar to what I posted in my
last email?

Thanks,
Jason
