Our company is having an intermittent problem when establishing a VPN tunnel.
VPN client: Cisco VPN client version 5.0.02 & version 4.7.00
VPN client config: IPSEC over UDP
Transparent Tunneling Enabled
VPN concentrator: VPN 3005, vpn3005-4.7.2.B-k9.bin
It's an intermittent problem. The VPN client will connect and authentication via RSA SecurID. The tunnel will become successfully established. However, no IP traffic will pass between the client and the "internal" network behind the VPN 3005 Concentrator.
When the problem exists, I examine the VPN Tunnel | Stats window.
It lists the following:
Does anyone have any idea as to where the problem may lie? It's pretty intermittent, but I does fairly often.
As always, thanks for your help.
