default route not set -- Why?? Options

[gmart]

I am new to Zaurus but very familiar with minimal Linux distributions.

I go to "Network & Sync" and setup a new service "USB-TCP/IP" with:

IP Address: 192.168.129.201
Subnet Mask: 255.255.255.255.0
Broadcast: 192.168.129.255
Gateway: 192.168.129.1

However, when I run a terminal session and look at the routing table
it only has the local network route and no default route!!

Why isn't the default route added ??
Specification of a Gateway address implies a default route.
What do I need to do to have it configured automatically?

It all works properly when I add the default route by hand.
(route add default gw 192.168.129.1)

I have an SL-550 with 2.38 ROM
