Create generic list of IP adresses in DCS 6.7

Hi

I want to create a generic list of IP adresses to references in a sandbox. (DCS:SA 6.7)

The Help guides does not describe how to create IP lists, only application list.

http://help.symantec.com/cs/DCS2.0/DCS2_0/v1074036...

I have tried as seen in the attached document. It doesn't seem to work.

1. Create a custom "list of items to be reference later". Named them Memberserver_IPs

2. Added 2 IP adresses. Value field = IP adresss

3. Used the parameter %gen_Memberserver_IPs_list% as Remote IP in a network rule.

4. Does not work.

Any tips on why this is not working?
