Background: Our WPMU site resides on it's own VDS server.
In Domain Mapping Configuration:
Admin » Network Admin » Settings » Domain Mapping
The instructions say:
On here you will enter the IP address which your end users will see within their own websites admin panel. This doesn’t really affect anything, it is really only for cosmetic purposes to inform your end users which IP they must use.
In the above, it says "this doesn't really affect anything - so I am unclear if it is possible to use different ip addresses for different network sites or if this is "just for cosmetic purposes",
If it is possible to use more than 1 ip address, can you please advise on how our server / ip addresses should be configured.
Our goal is to use the Domain mapping plugin - but associate each mapped network site with a unique ip address which is associated with a Satellite server.
Basically, configure Apache on the Satellite Servers, so that when domain searches terminate on Satellite Servers, the MYSQL look-up will be directed to the relevant files within our WPMU Network site (hosted on VDS server), rather than to MYSQL on localhost.
Any thoughts on approach are much appreciated.
