Synopsis: ipfw rejected packets respond port unreach instead of host State-Changed-From-To: open-closed State-Changed-By: alex State-Changed-When: Mon May 5 19:47:54 PDT 1997 State-Changed-Why: Ipfw's behavior is correct, see Stevens TCP/IP Illustrated Vol 1, section 21.10: "A received host unreachable or network unreachable is effectively ignored, since these two errors are considered transient. ... must not abort the connection. Instead TCP keeps trying to send the data that caused the error..." Reject should not put the remote host into a state of retry.
