    Hi,

    I've a DSL router with a firewall. Behind this
    router my Linux box is running.

    Nmap indicates the following ports:

    PORT STATE SERVICE
    21/tcp open ftp (this is my forwarded xmule-port)
    53/tcp closed domain
    113/tcp closed auth
    1720/tcp open H.323/Q.931
    61441/tcp closed netprowler-sensor
    65301/tcp closed pcanywhere

    Is it possible to get access to my Debian system
    through the router from outside? If so, how could
    an attack look like?

    Thanks
    Chris
