I have an Apache httpd v2.2 server (on Centos 6) set up as a forward proxy
to get to a DMZ in a test lab environment. It is working, but I would like
to restrict destinations to specific subnets, both IPv4 and IPv6. I've
searched for a solution and have not been able to find and answer.
Here is the virtualhost segment of my httpd.conf file:
<VirtualHost 10.10.10.185:8080>
ProxyRequests On
ProxyVia On
ProxyBlock "10.20.30.30"
<Proxy *>
Order deny,allow
Allow from 10.1.0.0/24
Deny from all
</Proxy>
ErrorLog "/var/log/httpd/proxy-error.log"
CustomLog "/var/log/httpd/proxy-access.log" common
</VirtualHost>
The above config allows incoming connections from the 10.1.0.0/24 subnet.
It does not allow connections specifically to 10.20.30.30 through the
proxy. Instead of blocking that single address, I would like to specify a
set of subnets that are allowed, and everything else be denied. For
example, allow:
2001:1111:2222:301::0/64
2001:1111:2222:302::0/64
10.20.40.0/24
But block everything else from passing through the proxy. I understand that
this would block any url that used a hostname instead of an IP address.
Thanks in advance for any help you can provide.

Mike M.
