Do I Need to Add a Route for an ECS with Multiple NICs to Reach the On-premises Network?

  • If the primary network interface card (NIC) is used to establish a VPN connection with the on-premises network, no route needs to be added.
  • If a non-primary NIC is used to establish a VPN connection with the on-premises network, add a route to the on-premises network with the gateway address of the non-primary NIC as the next hop.
