Block traffic to an external IP was created by gardmanit
Hi,
So I have a problem on my network somewhere that is causing me to get blacklsited from time to time.. its a needle in a haystack affair and I am working on this problem however in the mean time.. the CBL blacklist told me...
This was detected by observing this IP attempting to make contact to a Torpig Command and Control server on IP address 64.27.3.4, with contents unique to Torpig C&C command protocols.
Now I would like to block all internal traffic that tries to reach this IP address...
I have setup a Firewall Ip filter for this IP address (config below). Yet I can still ping this address, I expected a ping to fail because of the rule I put in place.. am I missing something stupidly obvious?
Thanks
Antony

Ok,
I found why it wasnt working.. Another admin had created a separate group with a rule stating ALL source ip to ALL destination IP allowed... thus overriding my attempt to block a specific.. and most likely making the router vulnerable
Thanks
