We’ve had an overwhelming response to our Direct Link product launch over the past few months and with good reason. Customers can cross connect into the SoftLayer global private network with a direct link in any of our 22 points of presence (POPs) providing fast, secure, and unmetered access to their SoftLayer infrastructure from their remote data center locations.
Many of our enterprise customers who’ve set up a Direct Link want to balance the simplicity of a layer three cross connection with their sophisticated routing and access control list (ACL) requirements. To achieve this balance, many are using GRE tunnels from their on-premises routers to their SoftLayer Vyatta Gateway Appliance.
In previous blogs about Vyatta Gateway Appliance, we’ve described some typical use cases as well as highlighted the differences between the Vyatta OS and the Vyatta Appliance. So we’ll focus specifically on using GRE tunnels here.
Many of our enterprise customers have complex rules governing what servers and networks can communicate with each other. They typically build ACLs on their routers to enforce those rules. Having a GRE endpoint on a Vyatta Gateway Appliance allows customers to route and manage internal packets based on specific rules so that security models stay intact.
GRE tunnels can allow customers to keep their networking scheme; meaning customers can add IP addresses to their SoftLayer servers and directly access them eliminating any routing problems that could occur.
And, because GRE tunnels can run inside a VPN tunnel, customers can put the GRE inside of an IPSec tunnel to make it more secure.
