Virtual NetworksNetwork Overlay

Trustgrid networks are assigned to Domains. They define an overlay network and routes for layer 3 connectivity. Trustgrid Nodes are then assigned to Networks. Virtual Networks Network Overlays work similarly to Amazon's VPCs but can span between clouds, datacenters, and between the cloud and the edge.

Virtual Networks

Virtual Networks - Layer 3

  • Trustgrid uses a Virtual Network to NAT traffic between Nodes. This avoids common challenges like conflicting subnets in large, non-centralized networks. 
  • Inside and Outside NATs are used to expose hosts for traffic
  • Routes may configured on the Nodes
  • ACLs can be applied

Simple Host Communication

  • An Inside Nat on the Edge Node that maps 10.0.5.250 to 172.16.3.250  would allow the Data Center host (10.0.1.150) to communicate with 172.16.3.250 host using the address 10.0.5.250
  • An Outside Nat on the Edge Node that maps 10.0.1.150 to 10.0.5.150 would allow the Edge host (172.16.3.250) to communicate the Data Center host at 10.0.5.150.
  • NOTE: A route would have to be added to the default gateway of 172.16.3.0/24 for 10.0.5.150 to route traffic for 10.0.5.0/24 through the gw of the Edge Node (172.16.0.5) data interface.

Virtual IP Addresses

Through the use of Inside and Outside NAT rules, local IP addresses to the Trustgrid Node may be exposed on the network through a Virtual IP Address.  For instance, a local device may have a local IP address of 192.168.1.100, but you may want it to appear to other devices or applications on the virtual network as IP address 10.0.20.100. Virtual IP Subnets are also supported where each IP in a subnet is mapped to the corresponding IP in a virtual subnet.
