ATA in front of router, why not?

[holmes4]

I found that my VOIPo service simply did not work when I put the ATA (RTP312) in front of the router. The service would go offline frequently. Too bad, as I would prefer it there.

I moved mine to behind the router because I felt uncomfortable with the passwords (two or more) being unique, proper, and controlled.

There's no means to to DYNDNS or equiv. This is a show stopper.

And other port forwarding and triggering capabilities are missing. The cascaded routers and double-NAT is hard to manage, for a home like mine that has 3 IP cameras, private, me-only HTTP server and FTP server.
