I have 3 Cisco VPN Concentrators that are load balanced. I have IAS configured on two windows 2003 servers for radius authentication. I need to start logging who and when logs into the VPN. I know to do this I have to setup an Accounting Server on the VPN Concentrator. The question I have is, do I choose the IAS server for the Accounting Server? If so are their any configurations I need in IAS? Can I log to another server besides the IAS server? I have a guide from Cisco here in front of me, but it doesn't go to far into setting up accounting servers. It just shows you where to go to add one, and it says to be sure that any servers you reference are properly configured. It doesn't say what properly configured means. Any help would be much appreciated. Thanks.
