No. The router portion of the ZyXEL exposes only the external IP; 
I didn't think any 192.168.x.x addresses could even be seen except on 
the LAN side of *any* router (as Alan states).

Alan, I don't see how this is any more "elegant" than what I've been doing all 
along. The Mac is already a true NAT router in and of itself, not a bridge. Its 
second NIC connects to a hub, and the rest of the LAN uses that interface's IP, 
192.168.2.1, as the gateway.

"Elegant" would be eliminating one or the other router and its address 
translation. John's is the elegant solution--change the netmask simultaneously 
with the Size of Client IP pool, and attach the ZyXEL to the hub. This relieves 
the Mac of its need for a second NIC, reducing rather than increasing the 
hardware involved.

Thanks to everyone for sharing your knowledge. The only unanswered question is 
how one would talk to the device at all if it became a bridge. That one's for 
ZyXEL.
