Static (incorrect) ARP entry

[Rolf Mendelsohn]

Hi Everybody,

I have a problem with a local ISP who use Alvarion WALKAir 1000 equipment, 
which does a sort of 50 / 50 routing / bridging.

The below is actually public addess space, just using 10 for clarity's sake:

Default Gateway: 10.8.16.1

The provider has given me the following information (changed to private IP 
space for security reasons):

Default Gateway: 10.8.16.1
My IP's: 10.8.23.121 - 126
Subnet Block: 10.8.23.120/29

This works 100% on a windows machine but does not work at all on any unix 
machines.

When my Windows 2000 box is plugged in I get the following:

C:\>arp -a

Interface: 195.8.23.121 on Interface 0x1000003
  Internet Address      Physical Address      Type
  10.8.16.1            00-03-40-9c-0a-99     dynamic

C:\>netstat -nr

How do I get a Unix machine to misbehave and accept a gateway which is not 
on it's connected subnet??? Is this happening because on Proxy ARP?

Any help would be most appreciated.
