Cluster Anti Spoofing

[galaxy]

We have a cluster with "Enable extended Cluster Anti Spoofing" checked, it appears to be dropping packets from a newly added internal network (not connected directly to an interface). I cant find however where we can add this network in so as it wont be classed as a spoofed adress. Does anyone have any ideas? I went into topolgy of the cluster object and clicked on edit to the interface but it doesnt list any networks.
Thanks.

Did you add new network to anti-spoof group for right interface?
If you have some networks behind network interface, you need to create objects for all this networks, create Simple Group and add all networks to it. Then select this group in Topology -> Specific
