Adding an Address Range to an Existing VPN

Hi there,

I need to add another IP range that is routable over the VPN I have setup within Azure, I only have access to the preview portal but I been introduced to a rather nice site that I'm sure you all know about already called https://resources.azure.com.

I'm told that I can add a the address range via this and I've found under localNetworkGateways the VPN settings like so :-

{
  "name": "LocalSite",
  "id": "/subscriptions/REMOVED/resourceGroups/CPSResourceGroup/providers/Microsoft.Network/localNetworkGateways/LocalSite",
  "etag": "REMOVED"",
  "type": "Microsoft.Network/localNetworkGateways",
  "location": "northeurope",
  "properties": {
    "provisioningState": "Succeeded",
    "resourceGuid": "REMOVED",
    "localNetworkAddressSpace": {
      "addressPrefixes": [
        "172.20.50.0/24",
        "172.20.51.0/24",
        "172.20.70.0/24"
      ]
    },
    "gatewayIpAddress": "REMOVED",
    "localNetworkSiteAddressSpace": {
      "addressPrefixes": [
        "(string)"
      ]
    }
  },
  "tags": {}
}

Now if I wanted to update the VPN to route an IP range 192.168.1.0/24 would I add it simply at the end of the addressprefixes and if so how would I restart the VPN connection to allow for the updated routes to take affect?

Thanks

James
