ASUS wireless AP (and ARP problem)

On the advice from an OP, I bought an ASUS WL330. My primary intent was
to bridge from one hub to another hub using a wireless connection rather
than a CAT 5 crossover cable draped across my hallway.

I've almost got things working, but not quite, probably because of an ARP
problem. Machine #1 is on main hub with nameserver, dhcp server, a
gateway to the internet, and a wireless access point.
Machine #2 is on a satellite hub with the ASUS WL330 doing the bridging to
the AP on the main hub. On #1, if I ping #2, I get a failure to
communicate. But on #2, I can ping #1. Immediately after I do that, I
can from #1 ping #2 (still in arp cache), but after a few minutes, the
cache is clean, and I can no longer ping #2.

Is there some setting on the ASUS that I have missed? (The instructions
for doing what I'm doing are quite vague and incomplete... You might say
I stumbled on the it working by tinkering.)

Still mystified by the ASUS settings, (Tom's Networking site confirmed
that their instructions are vague and confusing).

I've found that if I make arp entries, thusly:
arp -s dogbert 00:11:2F:0E:9A:1B
arp -s jupiter 00:11:2F:0E:9A:1B
where dogbert and jupiter are the two machines on the hub being bridged by
the WL330, (and the MAC address is the MAC of the WL330), that packets
will go from the main network over to the satellite and everything works.

Seems like there must be a more straightforward way so I don't have to do
arp entries on all the machines on the main network?
