Hello,

In the FreeBSD handbook, firewalls section, which I found on
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html
the following text is found in section 14.9.5.19.1:

- ---snip---
14.9.5.19.1 Assigning Ports to Use

BLAH

map dc0 192.168.1.0/24 -> 0.32

In the above rule the packet's source port is.....
- ---snap---

Does the BLAH have any meaning and if so, what is it?
If not, why is it there and shouldn't it be removed?

greets,
Erik Romijn
