Well... erm... change the gateway to be a device local to the
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
