setting up Proxy ARP

Hi everyone,
what a great list this is - its been invaluable in getting familiar with our new
pm10

In our Class C net I have a bunch of addresses assigned in a pool, but I do
not have them on a separate subnet. In our other dial-in device I set up
proxy ARP for the pooled dial-in addresses. However I do see a command
referenced on how to set up proxy arp for dial-in addresses.

Perhaps there is some other trick used (such as a 32 bit subnet mask), but
other devices on the LAN won't necessarily think to look up a dial-in host in a routing table, since they are on the same IP network. The proxy ARP worked
in this case because the dial-in router (telebit) returned its MAC address for ARP requests to its ethernet as well as the dial-in host addresses. Lots of
bad things happened when Proxy ARP was turned off.

So the question boils down to - is there a command to add proxy arp entries to the PMs arp table, or is this done automatically?
Thanks
John Jamison
