 ## IPsec tunnels using virtual network gateways
 
-In this option, you can provision a virtual network gateway in each virtual hub of your virtual WAN environment to connect virtual WANs together.
+In this option, you can use IPsec tunnels to connect Virtual WANs by deploying a virtual network gateway in each virtual hub withing your virtual WAN environment.
 
 Because the virtual network gateway ASN is always 65515, you can't have BGP over IPsec due to BGP loop prevention mechanism as the remote virtual hub will receive routes from the source virtual hub with 65515 in the AS-PATH and BGP will drop that. Therefore, if you want to connect two different virtual WANs, the tunnels must use static routing.
