Apparently, the "gateway" option invokes the BSD traceroute -g option:
Tells traceroute to add an IP source routing option to the out-
going packet that tells the network to route the packet through
the specified gateway. Not very useful, because most routers
have disabled source routing for security reasons.
I'm not sure I understand why the "interface" option succeeds (but
doesn't give my desired result), because it uses the next-hop in the
routing table which isn't reachable by the interface I specified.
"monitor traffic" confirms that adding the "interface" option does
send traffic out that interface.
If I add "bypass-routing" I get:
traceroute: sendto: No route to host
