Build filters on each serial interface of the router so that only
outbound packets originating from your corporate backbone are permitted.
(Or permit only inbound packets destined to your corporate backbone). If I
understood correctly, you are only building connectivity from
corporate backbone to each remote site, not trying to provide firewalling
between the remote sites.
