I'm not sure whether to try to get this working using reverse-proxy with mod_proxy, or perhaps some configuration using normal forward proxying. Perhaps even squid?
The requirement is to provide a simple initial main page that would allow the client to select a local interface from a drop-down list and enter a URL into an input field. Apache would then fetch the URL using the specified interface (eth0:1 at 1.1.1.1, eth0:2 at 2.2.2.1, eth0:3 at 3.3.3.1 and so on). This is the test how the remote site handle queries from specific source addresses.
So it's kind of like a normal forward proxy, except we don't want to have to configure the client browser to use a proxy.
1) Using mod_proxy and/or mod_proxy_http in apache 2.0.
The basics of using mod_proxy are pretty simple so long as you're using a static config. I'm trying to figure out how to do it dynamically - that is, allow the entry of a url via a form and proxy THAT url ...
ProxyPass /foo [foo.example.com...]
ProxyPassReverse /foo [foo.example.com...]
................................^^^^^^^^^^^^^^^^^^^^^^^^^^
................................This needs to be entered via form
This would be a simple page that has a drop-down list to select the outgoing interface (see part 2) and box to enter a url. Clicking the button would fetch the url using the selected interface.
2) Force a mod_proxy outgoing connection to use a specific local interface (eth0:1, eth0:2 and so on) each with its own IP address/network.
3) Perhaps use a small perl/php script to call wget to fetch the remote URL. Wget can specify the local interface to use for the fetch.
What's the best way to attack something like this?
