Description Divacky Roman 2004-09-12 15:40:12 UTC 
	The problem reported in bin/71490 was fixed by setting
	net.inet.ip.fastforwarding=0
	ie. by setting it to 1 (enabling it) the rdr doesnt work properly

Fix: 

I am not aware of any.
How-To-Repeat: 
set net.inet.ip.fastforwarding=1 and try to use rdr and/or ftp-proxy
Comment 1 Max Laier 2004-09-13 00:56:42 UTC 
This is caused by a superfluous byte order change in ip_fastfwd.c while the 
comment in ip_input.c clearly states what is expected:
    /*
     * ip_fastforward firewall changed dest to local.
     * We expect ip_len and ip_off in host byte order.
     */
