Samsung Smartcam no mails and relay mode

Hi, I changed my internet box, and now there is two things what doesn’t work anymore:
No email notifications with motion detect.
And relay mode appear when I want to “direct watch” via an external connexion.

Of course DHCP and upnp is activated, and it doesn’t work.
Do you know if I have to open some ports (port forwarding) ?


Sorry for my English, I’m french, and then it’s a french box (Freebox revolution)
