I'd like to gain some understanding of an existing rule on my firewall
that is allowing only a specific range if IP addresses outside.  This
rule was created by the previous network admin.

The rule is:
-A FORWARD -s 10.1.1.0/255.255.255.192 -i eth2 -j ACCEPT

I understand that the "/255.255.255.192" part of the above rule is
allowing only a specific range of IP addresses out to the Internet.  How
is this rule working and how would I expand the range or create an new
range?
