Preventing IPs from reaching server

[pmclinn]

I'm looking for some sample code that would show me how to prevent 2-3
ips from connecting to my server. Basically a very dumb firewall.

So the process would work like this...

upon request, on any port, the application would grab the users ip. If
it is one of the three blocked ips it would drop connection.

Any direction on this task would be appreciated.

Why not just buy a firewall, they only cost about £60

I want to add predetermined programmatic triggers, that will add people
to the deny list. And I do not feel like buying a good cisco router to
do it. Unless you know of another firewall, cheap, that I can ssh2
into and upload a new access list?

Looking at my current router logs there would be over a 1000 ip blocked
within the first day....

So far the code I have found just redirects users by ip on port 80.

This might do the trick for you , I think you can upload lists into it
