Re: Is there a workaround to use multiple source IPs in one Realm when I merge roles?
I'm not sure I understand your question.
All traffic for a session is initiated from a single address. When roles are merged, the first role that the user is assigned to sets the source IP address for the session.
Role merging is just what it says - the SA creates a merged role from the roles that the user is assigned to. That merged role cannot have multiple source addresses - how would the SA know when to source the data from one address or the other?
