I have 2 VPN 3015 Concentrators running a Load Balance setup. I want to add a new ASA 5520 to the Load Balance Cluster. When I enable the ASA to participate it sees the master VPN 3015 and goes into a backup role but then looks to lose connection and revert to a master role. It continues to go back and forth. I never see the ASA under my VPN 3015 Load balancing Statistics. Not sure what I am missing. The ASA is in the same networks as the Concentrators for both private and public interfaces. Same virtual cluster IP, using the same UDP port, same IPSEC shared Secret. Any direction on troubleshooting this is appreciated.
I have this problem too.
