I use a shell script to setup my ipfw3 firewall and want to define 
network lists to shorten my rule set. For that I used the approach 
described inside the example section on ipfw3 in 'man ipfw3'  like the 

	nets_allowed="{ or }"
	ipfw3 add allow log 1 ip in from ${nets_allowed} to

When I run this script I get the following error:

	ipfw3: hostname ``{'' unknown

Can you also reproduce this error?
