Has anyone run into this problem before?
Well... erm... change the gateway to be a device local to the realserver. I'm afraid this is a networking fundamental: the next-hop must be reachable! In your case you're confusing "gateway" with "default route". The realserver's default router to non-local networks must be reachable from the realserver, and that router must itself then have a route to "the internet" - 0.0.0.0/0 - which is itself reachable. And so on, and so forth. IP 101, I'm afraid.
