    Smile Is my router secure?

    My ISP was blocking ports. I asked them to unblock the ports so now we have set all of the port blocking handling to the router we have here at home.
    So my question is, is my system secure? Anything I should be aware of?
    And if my computer isn't behind any sort of firewall, just straight connected to the Internet (demilitarized zone?) is it secure? does it impose any security risks?
    I'm running ubuntu 12.04 and the others in the house are using windows 7
    Btw I have uPnP enabled.
    Sorry for being such a noob..

    The best situation would be to have a firewall on your router. Even if you do, it still requires knowledge to set it up, properly.

    If you do not have a firewall on your router, then you should have one on every LAN host.

    This is my opinion and I am sure you will get differing opinions from others.

    Depends on the router, and how you have it set up.
    Is it store bought?
    Have you customized it?
    Have you changed the settings?
    Is it home built?

    Generally, the default settings of common routers are safely. There is no waste of time in give some check to the security setting.

    I think that in main way, you must worry about your router in particular (brand/model) and search for possible bugs and security holes. Of course, always having the latest firmware.

    One piece of wisdom I recently read (citation needed) is to turn off uPNP on publicly-facing routers if you don't need it.

    +1 to this, UPNP has been instrumental in opening the built in VNC server to the internet on at least 2 systems I've seen that have been owned. While I recommend not running the VNC server if it is not absolutely required, UPNP can definitely add holes to your security.
    Can't think of anything profound or witty.

    Yup, uPnP is not great for security; It's 'OK' if you vouch for everything that's going on internally.

    Unfortunately, many things are designed with uPnP in mind, and it can make things much more convenient - there's always a trade-off. I leave it on, because our home router handles connection from many, many things, and life is too short.

    Re: Is my router secure?

    Ok, so I may want to turn off the upnp feature. I hear that this may cause problems with network printers? We have one. Anything else that it may disturb?
    I updated the firmware on the router. I'll disable it for now. If I get any problems I might enable it again.
    Thank you all very much for your help

    It will disturb anything which uses uPnP to automatically forward ports, which for many people, is nothing much at all. It won't cause any problems unless you're accessing your printer externally, which I imagine you are not. Torrent client and VNC servers will generally use uPnP; IM clients may use them.

    Bottom line: if something needs uPnP, you can manually create a rule to forward the ports.
