if you can connect to the wan interface on your router the easiest is to run nmap and nessus

it appears you are using some sort of linux, as an added measure once finished nmap on router from your pc that is connected to it to establish what ports are open. in a terminal type in
#iptables -L ( this will list your rules)
eg If you wanted to block all incoming telnet connections to your computer:
ComputerName:~# iptables -A INPUT -j DROP -p tcp --destination-port telnet
Since there is no defined source, any telnet request to your computer will be blocked. you can replace telnet with say ftp or http or ssh or whatever you want to block.
#iptables -F will flush out those rules.
