Remote Access through a firewall
« on: April 28, 2011, 04:47:58 pm »
I can access my Vera 2 from the outside, after logging on to mios.com. My Vera is behind a firewall; can someone explain how the remote access can get through this firewall? I have a VoIP phone behind my firewall too, that can be called from the outside; it uses the SIP protocol when it is first connected. Does Vera do something similar? Thanks.

Joe.

Quite similar...

As for the ATA device (for your phone), the Vera is the one establishing the communication using a NATing process through your router. In other words, Vera is the one running the show, not MIOS.com

To add to what huogas said;  Look at it like this.  Even though your computer is behind a firewall, when you open a connection out to a web page, the data from the page is allowed back in. 

Vera works in a similar way, it establishes a connection out to mios.com that mios can then use to send traffic back in to Vera. 

It's not a function of NAT, but more along the lines of a stateful connection.  NAT is used, but only for normal traffic translation.   NAT is the process of taking internal private IP addresses and translating them to the public IP address that exists on the external interface of your router.

Right!. Thanks for the correction.
