I have difficulties connecting to Cisco VPN 5000 .I am using VPN 5000 Client
behind NetScreen 25 firewall with policy based NAT . I have opened UDP/500
IP/50 and ip/51 to pass trough on NetScreen device. If " NAT transparency mode" on VPN Client is enabled i can't establish connection with VPN concentrator . If "NAT transparency mode" is disabled i can establish VPN connection but can not access resources on remote site .
I would be grateful for any suggestion on that issue !
