RSV4000 - multiple users in same location doing VPN

[idepix1809]

Hi,

I've been able to configure the VPN on a RSV4000 device. I have 2 Windows 7 clients that connects in that VPN.

Everything works well except when both users tries to connect at the same time, they both kick each other out the VPN.

They are behind the same Dlink DIR-615 router (at home) and has differents subnet than the 4000. I'm suspecting the fact that that router receive 2 demands from the same IP, is there an option to allow that on the 4000?

I've also find an interresting post on Microsoft support but it applies to Vista, not sure it applies to Win7.

Thanks for your help,

Ben

The connexion works but when another client tries to connect, it fail.

I tried to open ICMP request but no luck. I can ping sucessfully the router  throught the WAN.
