The answer is that you need to configure Buster to function as a router.
 Just configuring Buster to be a part of both networks does NOT mean that
Buster will automagically send packets originating on one network to the
other network.

There are several ways to accomplish this.  You can enable IP Forwarding,
as suggested, or you can run routed, an IP routing daemon.

Since you only need to forward/route the one segment, IP Forwarding will
be much more straight-forward, although every host on your 10.42.42 subnet
will need a static route to buster for the 10.42.43 subnet, otherwise, they
will send everything to the firewall, and the firewall will put it back on
the 10.42.42 subnet addressed to buster (provided you have that rule configured
on the firewall).
