I have a DSL line going from a DSL dumb/bridging modem to a GNU/Linux box. The GNU/Linux box does the login/authentication for PPP and is assigned a public/valid IP address to its network card.
This is a requirement for me. The GNU/Linux box has to be reachable via its public IP address from the Internet.
If I attach the Telo to the DSL modem and put the GNU/Linux box on the Telo's Home Network (as per the Setup Guide's "Alternative Setup Options" Option A or B), ooma will "work" -- I get a dialtone can make a call. However, in this configuration, the GNU/Linux box is assigned a private 10.*.*.* IP address. This is a show-stopper for me since the GNU/Linux box needs to be accessible via the DSL line's public IP address from the Internet.
If I attach the Telo to a network switch inside the firewall, the Telo just blinks a continuous red light (not surprising since there is no DHCP server to assign it an address and no incoming ports open for the Telo on the firewall).
My questions:
Overall my question is: How can I make the Telo work in this network? (Again, the GNU/Linux box must get a valid/public IP address and be reachable from the Internet.)
I'm guessing this cannot be an uncommon problem. Any advice would be greatly appreciated; thanks.

- Is it possible to set a static private IP address (and netmask and gateway) on the Telo?
Could the Telo be convinced to work inside the firewall by having a DHCP server assign it a private IP address?
What incoming ports will the Telo need open to receive phone calls?
I'm guessing this cannot be an uncommon problem. Any advice would be greatly appreciated; thanks.
