Hello, im trying to open port 21 to use an FTP server, i can't seem to get port 21 open my setup is as follows:

[DSL MODEM] > [Ooma] > [Router]

Do i have used port forwarding rules on both my router and ooma. do i have to change my router from a dynamic ip to static or what? or maybe open a DMZ. Please someone help me

Configure ooma's DHCP start and end addresses to be the same IP address.
Put that IP address in the DMZ field.
Set ooma to use the built in MAC address.
Set up the appropriate port forwarding on your router.
FTP uses ports 20 and 21.

I have tryed all this, and yet my port 21 is not open. Do i have to set a DMZ on the router too?

You do not want or need the DMZ on the router to be used.

How are you testing? It can not be tested from inside your network because the hub does not support loopback. Your testing must be done from an outside computer.

You can make your life a lot simpler by putting the ooma hub after your router. That is where mine is and it works fine.

if i did this, do i need to open ports on the router for the ooma to work?

No, unless you have outbound ports blocked. That is highly unlikely in a residential router.
