... what exactly is the website? What is the site driven by? PHP, CGI, ASP,...?
Where are they trying to post? upload with ftp? spamming a 'contact us' form?

your going to have to explain the situation a little...

I don't know what they try to post. What I know is that one posting url is targeted by those IP addresses. They keep hitting the url and the url only. They are blocked by login requirement.

Another type of attack I notice is that the sign on form is a under attach too. The url is hit by a pair of user name and password many times a day.

If your server is properly secured, I wouldn't worry about unsuccessful attacks (which I assume these are). Only worry about the successful ones.

I agree... Your doing all you can. You are stopping the attacks. There is nothing you can do to block incoming connections. You might try and add some sort of "you've used up your failed login attempts" feature or something...

if you really really hate the connections...:
The other thing you could do is block all IP's except for the IP's of known valid users... Of course this inst all that plausible with dynamic IP's, but you could create some sort of uploader that the clients could install and update your allowed users list...
