Virtual routers provide L3 services such as routing and Source Network Address Translation (SNAT) between virtual and physical networks, or different virtual networks:
- A virtual router between virtual and physical networks provides access to public networks, such as the Internet, for VMs connected to this virtual network.
- A virtual router between different virtual networks provides network communication for VMs connected to these virtual networks.
A virtual router has two types of ports:
- An external gateway that is connected to a physical network.
- An internal port that is connected to a virtual network.
With virtual routers, you can do the following:
- Create virtual routers
- Change external or internal router interfaces
- Create, edit, and delete static routes
- Change a router name
- Delete a router
- A router can only connect networks that have IP management enabled.
- You can delete a virtual router if no floating IP addresses are associated with any network it is connected to.
