Procedure:
1.	Upload the script to your TMG
2.	Edit your main script (ex. simple_routing.rb) and add what is below (it’s like adding nap_group_weight_load_balancer to a script)
    a.	require ‘multiple_naps’
    b.	include MultipleNaps
    c.	before_filter :method => :multiple_naps
3.	Create a new custom column
1.	“additional_naps”, type “text”
4.	In your routes, add a regex in the new column which will match the additional NAPs you want
1.	/GROUPA_.*/


The trick is to use the NAP names to identify which NAPs are in the same group.  The example in the file talk about "SIP_.*" but I would use instead "/GROUPA_.*/".

For example:
GROUPA_SIP_NAP_10_10_10_10
GROUPA_SIP_NAP_10_10_10_11
GROUPA_SIP_NAP_10_10_10_12
GROUPB_SIP_NAP_10_10_20_20
GROUPB_SIP_NAP_10_10_20_21
GROUPC_SIP_NAP_10_10_30_30

Then, in your routes, you can use the Route Column "additional_naps" to put /GROUPA_.*/
