missing parameter in book for ipsec

[Todor Dragnev]

Hello, 
I found missing paramet for ifconfig in document with url

 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ipsec.html

the right command line for ifconfig must be 

ifconfig gif0 tunnel A.B.C.D W.X.Y.Z

wrong block:
===
On the gateway machine on network #1 you would run the following two commands 
to configure the tunnel.

>>>> ifconfig gif0 A.B.C.D W.X.Y.Z
ifconfig gif0 inet 192.168.1.1 192.168.2.1 netmask 0xffffffff
     

On the other gateway machine you run the same commands, but with the order of 
the IP addresses reversed.

>>>> ifconfig gif0 W.X.Y.Z A.B.C.D
ifconfig gif0 inet 192.168.2.1 192.168.1.1 netmask 0xffffffff
===
