Hi,

Does any one know whether Ipsec VPN connections work simultaniously from multiple cisco vpn clients to the same concentrator through Dlink (DI-704P) gateway router?

regards,

jimmy.

I myself have not tried use DI-704P gateway router. But I have done some search for that router, got following information:

"The DI-704P provides special pass through function for common VPN implementations including PPTP (Point to Point Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol) and IPSec"

Our concentrator support "IPSEC over UDP" and "IPSEC over TCP" function, so as far as DI-704P support normal NAT ( I am pretty sure it does), we can use VPN 3000 and Cisco VPN client this special feature to make mutilple VPN clients passing through the DI-704P router to connect to remote VPN 3000 concentrator.

More details please see:
