VPN 3000 concentrator IPSec/LAN-to-LAN 85%

[sivakumar.ks]

Hi,

I am using VPN concentrator 3000series for terminating VPN connection. At present on average 14 IPsec tunnels are connected 24/7 basis and few webVPN users so in total average VPN termination connected through VPN concentrator is arround 16. On monitoring protocol under session tab IPSec/LAN-to-LAN percentage is 85% and during peak hours it is exceeding 95%. I need to fix this problem inorder to connect more VPN sites through concentrator.

Please guide me what to do ?

My software version is vpn3000-4.7.1.Rel-k9.bin

Thanks,

siva
