Default Deny Specific Incomming IP to Webserver

I would like to be able to deny specific IPs from ever hitting my Apache web
server. I can Deny them via the httpd.conf file, but that only stops them
from getting my pages, they still know the server exists.

I tried via the IP Security Policies in MMC but my test computer still
showed up in the Apache log. Since I have port 80 forwarded through my SOHO
router to my WebServer, is it possible to actually deny a specifi IP from
seeing open port?

Any suggestions of a non overly intrusive software firewall, or a built in
ACL, or filter would be greatly appriciated.

Ipsec should work if configured correctly and will block the IP at the
network layer before the application ever sees it. The link below may help
with ipsec filtering policy configuration. Your SOHO router may or may not
be able to do what you want depending on it's capabilities. "Real" firewalls
would allow you to add a firewall rule that blocks access from a specific IP
and the ordering of firewall rules is important to make sure the more
specific rules are processed before the general rules. Ipsec rules are not
dependant on the order they are listed but instead are assigned a weight
with more specific rules taking precedence over general rules. Let me know
if you still have problems with ipsec. --- Steve

Steve,

While I am reading the page you sent me, I wanted to let you know that
my SOHO is a Linksys BEFCMU10. It appears the the FIREWALL portion is only
for outbound..Seems odd that it wouldn't filter inbound

Trying to keep your ISP from discovering you have a web server ?

I know Comcast in the past has often probed looking for that sort
of stuff.
