Linux router being attacked

Hello,

I have an Ubuntu v12.10 with Shorewall.  On one of my Windows Server 2008 R2, I have Spiceworks installed.  Spiceworks tells me that a questionable IP address is communicating with the router.  I blacklist the IP addresses as quickly as I can.

I am wondering if there is a list of questionable IP addresses somewhere?

Thanks in advance.

Have a great weekend,

Don

Are you asking for if there's any public black list of IP's?

If that is your question, here's the link but I'm not sure if that's going to help since there are too many IP's and you won't be able to block them all....

Yes, that is what I am asking, but you're right!  Soooooooooooooooo is there a way I can defend my router from questionable IPs?

Normally, firewall vendors have built in database of known bad IP addresses and block them and also they update the database automatically.
I'm not sure if Shorewall has IPS feature but you might want to look into that.
