There are times when we need to build connectivity between Aviatrix Transit and Azure VPN Gateways. I’ve created a terraform module for a quick lab demonstrate how this can be done.Continue reading
When working with Aviatrix Site to Cloud Connections, it could be confusing to understand how tunnels are established. I will take you through three scenarios and hopefully help to planning to Aviatrix S2C connections with other vendors.Continue reading
Aviatrix Controller isn’t In data path, controller down will affect ability to change currently configuration, or to monitor gateway status to make changes to route tables, or to authenticate new VPN user connection request.
To make sure Aviatrix controller in AWS highly available by avoiding single AZ failure, Aviatrix has developed a CloudFormation template that utilizes Auto Scaling Group and Lambda function to automatically monitor controller failure, redeploy controller and restore configuration.Continue reading
Here’s a case where customer wants to create BGP over GRE tunnels between Palo Alto Firewall and Aviatrix Transit Gateways. Palo Alto have some articles but not very clear, this blog will serve as a reminder how this is done. Credit to Pranay for helping out the BGP peering part on Palo.Continue reading
This is the first of the three articles. It will be the easiest to accomplish but with following requirements, and constrains highlighted.
- Virtual Private Gateway (VGW) has to be created in the same region as the Direct Connect Private Virtual Interface (VIF).
- Each VIF is dedicated to one VGW.
- VGW is NOT attached to the VPC
- Aviatrix orchestrate Customer Gateways and VPN Connections, building 2x IPSec/BGP tunnels per Aviatrix Transit Gateway.
- Each IPSec tunnel have 1.25G throughput limit
- Private Virtual Interface support up to 100 BGP routes, BGP session will go DOWN when more routes been advertised. In layman’s term when this happens, Cloud won’t see OnPrem routes, and OnPrem won’t see Cloud routes, connectivity between Cloud and OnPrem will be LOST. You must summarize advertised routes on both ends to be lower than 100 to get around this limit.
- Between On-Premise to VGW, traffic maybe protected by MACSec, but still expose to man in the middle attack. Reference article: Securing your network connection to the cloud: MACSec vs. IPSec
When customers are migrating to Aviatrix Transit from AWS TGW, we would build BGP connectivity between AWS TGW with Aviatrix Transit. In the past, we have to use IPSec, which would be limited to 1.25G per tunnel connection speed, for customer’s that doesn’t require end to end encryption during the migration, with AWS TGW Connect, now we can build GRE tunnels between AWS TGW and Aviatrix Transit.Continue reading
Many enterprises venture into clouds and find the landscape of cloud networking very different from on-prem. Multi-homed devices such as routers and firewalls when deploy to the cloud also are having challenges to insert themself into traffic path, particularly due the reasons listed below. This in turn slows down the enterprises adoption speed to the cloud. Let’s take a look what some of these challenges are:Continue reading
One of our customers are looking to use Aviatrix to automatic their self-service process for AWS China region.
The issue they are running into, was the terraform init would fail 50% of time. Is there anything we can do to help in this situation?Continue reading
