NETGEAR DGN2200v4 VPN CREATION ERROR

[gabrifolle]

I've a problem during VPN creation. When I create a VPN after the VPN name and key I've received the error in the picture.

Can someone help me?

Thanks

Did you try to do this using different web browsers?

Really thanks for the reply.

Yes, I've tried with Firefox, Chrome and Explorer. No way, same ansewer. There are maybe some ports that must be open to the router lan ip?

Thank you very much!
