Router Security

I read somewhere that This setup:
Upstream <--> Ooma <--> Router <--> Rest of house
ooma makes router inaccessible from outside world.

If that is true, then there is no need to secure your house Network with Ecryption, is there??

That isn't really true because you are still susceptible to direct attacks on your PCs based on the services that you run such as a Web Browser, IM clients, etc.

It is often said that any router type device doing NAT (Network Address Translation) is secure but if you search you will find NAT is helpful, but not totally secure.

From a traditional firewall viewpoint, a single layer of NAT is adequate, however, most problems these days are not due to ports left open or services that are cracked by bruteforce, although those exploits do still exist. It's usually the deployment of an agent through spyware or other various flavor of malware that is going to be your problem, and a passive firewall does nothing to protect you from that.
