Setup: 2 Webservers pointed to 127.0.0.1:8080 and :8081. Curl validates they work as expected. Apache with the following virt hosts:

NameVirtualHost 192.168.1.1:80

<VirtualHost 192.168.1.1:80>
  ServerAdmin [email protected]
  ProxyPass             /       http://127.0.0.1:8080/
  ProxyPassReverse      /       http://127.0.0.1:8080/
  ServerName 192.168.1.1
  ServerAlias http://192.168.1.1
</VirtualHost>

NameVirtualHost 192.168.1.2:80

<VirtualHost 192.168.1.2:80>
  ServerAdmin [email protected]
  ProxyPass             /       http://127.0.0.1:8081/
  ProxyPassReverse      /       http://127.0.0.1:8081/
  ServerName 192.168.1.2
  ServerAlias http://192.168.1.2
</VirtualHost>

On the server I can curl to the virtualhosts and receive appropriate responses. (curl 192.168.1.1 gives me the webservers response from localhost:8080, etc)

remote hosts cannot however connect to 192.168.1.1 or .2 at all. What am I missing?

Re: comments

Yes, the default directory Directive is still in place.

# Deny access to root file system
<Directory />
        Options None
        AllowOverride None
        Order Deny,Allow
        deny from all
</Directory>

No apache logs are generated when trying to reach 192.168.1.1 remotely. They do get generated when curl from local.

If I point the webservers to *:8080 and *:8081 instead of binding to localhost, I can access them from a remote host via 192.168.1.1 and 192.168.1.2 if i specify the 8080 and 8081 ports (both ports work on both IP's, which is what I'm trying to avoid with apache reverse proxy bind to 80 on each interface)

Edit2:

curl verbose output: (similar for second webserver, and for 127.0.0.1:portnum)

[user@host mingle_12_2_1]$ curl -v 192.168.1.1
