So how do you know what your IP is if it changes from your ISP?

I get the router's ip address (that the ooma hub servers) from the router config application, and then use that address to go to the gateway, which is the ooma box, by substituting the last sub-part of the address with a "1". So http:n1.n2.n3.1 gives me the ooma box setup screen. then I click "status" and my ISP provided ip address shows up under "modem".

Ok I did this and it shows a different Ip than it says in my router set up. What could be up?

It should match the address beside Modem in the ooma setup.
The way you get to ooma setup is:

http://setup.ooma.com

I'm assuming that ooma is ahead of your router.

So you don't access your network away from your network. That was my point. If you are away from your network, and are trying to log into a (pick it: server, ftp, RDC, VPN) you need the IP address from the ISP and you can't get that.

The biggest argument for having the OOMA behind the router is because we have a dynamic IP address from our ISP.

And without running a separate client 24/7 to update the DNS then you can't access your network or web page etc.

Using DDNS on the router is a simple cost effective way of doing this.


My question was how do you connect from the outside if you dont know your IP when your outside the network.

The address in the web is your "front facing" IP address. This is the address given to you by your ISP.
For you to have a different IP, your router must be behind either another router or the OOMA hub

Yes, I access my home network from anywhere on the Internet, and the procedure I put in the earlier post is how I find out what ip address to use to connect to my home network.

As others have noted, whatismyipaddress is an easier way to get this.

At any case, you can log into the ooma box from anywhere in your home network by using the gateway address of your ooma box. E.g., if you're router gets a DHCP address from ooma of n1.n2.n3.37, you can connect to the ooma box with n1.n2.n3.1. This gives the same results as putting a PC behind the ooma box and typing setup.ooma.com as the url.)

I hope this helps someone thinking about using ooma. It's great and I am very glad I found out about it. My port request has been submitted...

192.168.*.* is a class C private address--16bit--which many of us uses
what ooma uses is a class B private address (started at 127.16.0.0/20 bit)
there is another class A private address with 24 bit, started at 10.0.0.0

see the link IPv4_private_addresses

Anyway, as long as ooma works, who care which address it uses.

lohertz is right.

this will give your ip address when your're at home. When you try to connect to your home network from the outside, this ip may still be remain the same or might change. This probably works if you put the whole gig on UPS. Any hiccup in power supply will cause the modem to reboot and has a new ip assigned.
