Getting Apache *outgoing* proxy connection on virtual IP interface.

Can't find any reference here or on Apache docs.

Hi,

I'm configuring a new machine which has a single physical interface but multiple virtual interfaces (ie additional IP addresses).

The machine is also to be a proxy, but for historical reasons the machines *main* address is completely firewalled so I'd like outgoing proxy connections to be made using one of the virtual IP addresses which is not firewalled.

I can't for the life of me see where this is documented (for Apache 2.x); can someone point me to a URL or tell me.

Rgds
