If you are running the sv on your home, be sure to also enable the ports on your router config, maybe you only will need to do this and not configure the firewall (ubuntu has all ports open by default):
Maybe this helps: http://www.computerhope.com/issues/ch001201.htm

Else:

Depends on your Distro, usually ubuntu has ufw and then you can do it easily:
ufw allow 8303

Or maybe you are using iptables:
iptables -A INPUT -p udp -m udp --dport 8303 -j ACCEPT
service iptables restart
