Should I enable or disable the firewall if I'm using an external router?

Should I leave the firwall enabled or disable it if I have wifi off and only using an external router with a firewall?  Generally, I would disable it if I'm using the another modem device like a DSL ...

    For all intents and purposes you're behind a double-NAT on satellite.

    Unless you have hackers in your house using your local LAN, I wouldn't worry about the firewall much. Think they just included it because it was part of the router firmware.

    Think you're safe leaving it disabled, unless you want to use the parental features, etc. underneath it.

Leave it enabled if you are using IPv6, as all IPv6 addresses are supposedly routable.

It's included for SME customers, as they can get a routable IPv4 address and perform port forwarding... While the firewall features are ultra basic... It is pretty much a needed thing to keep ports closed to the outside world.

I originally thought so as well, but neither IPv6 address is.

 

Edit: Forgot about SME though... that's a different story.
