Hi,

I am trying to set up a "simple" AIX DHCP server directly connected to
W2K/NT Clients (no routers). Everything is properly connected, but the
W2k client always return "unable to reach DHCP server". I am using AIX
4.3.3.11.

Using the DHCPSD log file, we can clearly see the DHCP protocol being
done correctly (DISCOVER-OFFER-REQUEST-ACK), but the server ACK
doesn't seem to be well received by the client. Here is a portion of
the log file:
----
[...]

------
The client is always requesting the IP address and finally timeout.
What's wrong?

I've read that we need to add a 255.255.255.255 route to the host when
using Windows DHCP clients. How can we do this in AIX? When I try
"route add -host 255.255.255.255 -interface en1", it says
"255.255.255.255: bad value".

Can anybody help me?

Thank you

Martin
