IPsec VPN split with routing for specific outside IPs

[radioouman]

I need a little help setting up a VPN connection that allows access to the local LAN and some outside websites, but is split so that most browsing is done from the client's local internet connection.  (We have access to a few outside websites that are configured to only allow our office IP address to connect, so I need to tunnel through the VPN to access those.)

I have created an IPsec tunnel which gives access to the local lan and is split for local internet browsing. 

I was also able to create a separate L2TP over IPsec tunnel that forces all traffic through the tunnel which allows access to the external websites that we need.  But I don't know how to configure our Fortigate 90D to route traffic for those external websites through the VPN.  Can anyone help?
