Foreman » Smart Proxy

Behaviour: In the UI, clicking Import Subnets goes to a page with the Gateway and Netmask correctly detected/filled in, but not the Start/End IPs according to my pool. If I hit the API, I see:

root@test1:/var/log/foreman-proxy# wget -q -O - http://localhost:8000/dhcp
[{"network":"10.10.0.0","netmask":"255.255.255.0","options":{"routers":["10.10.0.1"]}}]

Setup: Debian Wheezy with backports, packaged 1.11 RC3 proxy.
