Every machine on a network can have a firewall.  I think the default
set up for Ubuntu/Debian is to have no firewall enabled (Ubuntu
Desktop definitely has no firewall on by default).  So, it's possible
if you have a firewall on your computer that that's why it's not
working.  Try running the "sudo iptables -L -v" as recommended and
confirm whether your system is blocking anything or not.  If that
command doesn't list anything, then it's not a firewall issue.
