[maemo-users] issue with incorrect IP routes being created

I have connected my new Nokia N810 to my local wi-fi network.

It is mostly working fine except that it appears to have installed a
spurious route whish is effectively blackholing some traffic.

I have the N810 configured to use a static IP address for my local
wireless (wi-fi) network.  For the sake of argument let us say this is with a netmask of  The gateway for this
network is

The connectivity mechanism correctly generates a default route via for the wlan interface.
However it also generates another route to with netmask

Consequently all packets to addresses 11.x.y.z apart for the local
network are effectively blackholed.

The routing table is (anonymized) ..
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface        *            U     0      0        0
default         router.exampl.c         UG    0      0        0

This is clearly incorrect as the local network is not a /8.

Is this a bug in the udhcpc postconfig script when used woth a static
address?   I can't actually find this script to check.

Any help would be appreciated.
