Hi,
I screwup my dhcp server on sme, configured at a standalone server. I disable DHCP by mistake. I thought that another server was providing the dhcp services.
Disabled with 
config setprop dhcpd status disabled
service dhcpd stop
then when I realized my error, I tried:
config setprop dhcpd status enabled
service dhcpd start
Now I get the IP address with correct subnet mask but not the gateway nor the default route.
I also tried as 'admin' and the admin interface to enable the dhcp service, same.
show dhcpd status
dhcpd=service
  Bootp=deny
  end=192.168.1.192
  start=192.168.1.121
  status=enabled
Any suggestion on how to fix it.
