Is it possible to filter access to directories in Apache via ProxyPass or proxyPassReverse in mod proxy.

For example I have a server with two interfaces. and lets say
Anyone coming to the server from I dont want to give access to the admin interface and anyone coming from I do want to give access to the server.

Lets say the directories are test and test/admin

You can achieve this simply by iptables

iptables -A INPUT -d --dport 80 -j DROP

iptables -A INPUT -d --dport 80 -j ACCEPT

Some more info.

Lets see if I have this right.
You have an apache server with 2 nics
Nic1 has IP
Nic2 Has IP

If a user hits IP Address then allow access to test AND test/admin
If a user hits IP Address then only allow access to test and OT test/admin

You can do directory level access when you know the IP of the host
Allow from

can you have it so a know list of IP Addresses can get access to the test/admin and everyone else is denied.

eg: (this may not be 100% but you get the idea)
<Directory /path to web folder/test>
     Order Deny,Allow
     Allow from all
<Directory /path to web folder/test/admin>
     Order Deny,Allow
     Allow from <ip 1> <ip 2>

I think m_walker had the correct answer to your question.

You configure your proxy just like a normal apache directory as he stated. The specific example used on the mod_proxy website is.

<Proxy *>
Order Deny,Allow
Deny from all
Allow from 192.168.0

If you would post your proxy configuration directives it would be simple to give you exact changes required to achieve this result.

You may want to try something like this
RewriteCond %{REMOTE_ADDR} !^1\.1\.1\.1$

farzani:  I think the filter needs to be on the apache server IP that the user hits,not the users source IP.  

eg: On my my computer I have IP Address of Then I could and since I hit the server IP then I can Access the admin folder.  But if I go to then I cant get access to the admin folder.  So the rule needs to use the apache serveres local IP.

I am assuming there are other things in place that will manage who can route to each interface, so the 10.1.1.x/24 could be the admin network.

That said I'm sure you will know how do to it :)
