If I have understood your case this cannot be done. You need to advertice the remote location with a host route. i.e more specific than the whole subnet. ip route next-hop.

The only way to achieve this is by bridging the 2 locations. However, I don't recommend this approach since you will be extending your Layer2 over a WAN connection.

Even if you were to assign an IP address on that server and transport it over to the remote location, when you ping the server from HQ to the remote location, the packet will never get there since the HQ device will never ask the HQ router to 'route' the packet. The packet will remain within the HQ network.

You need to investigate if it's possible to cluster servers while on different subnets.
