DHCP networking problems after upgrade to woody

[Peter S Galbraith <GalbraithP@dfo-mpo.gc.ca>]

I got my ADSL line last night, ran '/etc/init.d/networking start'
and proceeded to download 240MB in 28 minutes (!), and upgraded
my Progeny to woody  (I didn't change the kernel, running 2.2.18).

Now the ADSL network won't work anymore.
Running either pump or dhclient now gives me the same IP:

eth0      Link encap:Ethernet  HWaddr 00:01:03:1E:1F:E9  
          inet addr:192.168.1.2  Bcast:192.168.1.255
          Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:3213 errors:0 dropped:0 overruns:1 frame:0
          TX packets:376 errors:0 dropped:0 overruns:0 carrier:5
          collisions:0 txqueuelen:100 
          RX bytes:623395 (608.7 Kb)  TX bytes:110602 (108.0 Kb)
          Interrupt:10 Base address:0xb800 

Running dhclient verbose says that I got IP 192.168.1.2 from 192.168.1.1 :

 DHCPDISCOVER on lo to 255.255.255.255 port 67 interval 7
 DHCPREQUEST on eth0 to 255.255.255.255 port 67
 DHCPACK from 192.168.1.1
 bound to 192.168.1.2 -- renewal in 60 seconds.

This is reserved adress space for internal nets, right?.  Is my own box
somehow providing an IP adress that I don't want?  (I have both
pump and dhcp-client installed, but no server.)

I wish I could get my network back and wish I hadn't upgraded.
Any help appreciated!
