I think this is a reasonable thing to allow to be fixed in the Neutron
client. The workaround of clearing the gateway can result in losing the
fixed IP to other ongoing requests.

Title:
  unable to update enable_snat using router-update command

Status in neutron:
  New
Status in python-neutronclient:
  Confirmed

Bug description:
  Currently enable_snat is allowed only when setting a gateway.

  $ neutron router-gateway-set <router-name> <ext-network> --disable-net
  $ neutron router-gateway-set <router-name> <ext-network> --enable-net

  There should be provision to set this flag with update command too.
  Like
  $ neutron router-update --enable-snat
  $ neutron router-update --disable-snat

  
  On Neutron, with the below command:
  curl -g -i -X PUT http://10.0.4.130:9696/v2.0/routers/deecfcf8-6a4d-494d-938e-515f5c9d5885.json -H "User-Agent: python-neutronclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: b964f5aed06147efa06d27392db4f4f4" -d '{"router": {"external_gateway_info": {"enable_snat": false}}}'

  Actual Response:
  HTTP/1.1 400 Bad Request

  {"NeutronError": {"message": "Invalid input for external_gateway_info.
  Reason: Validation of dictionary's keys failed. Expected keys:
  set(['network_id']) Provided keys: set([u'enable_snat'])."

  Expected Response : That the external_gateway_info would have the SNAT
  disabled, even without the gateway network ID

  
  In Other words, 
  Expectation is that user can be allowed to enable/disable SNAT independently if the External Gateway Network ID is set. If not,
  then it should be avoided
