Question

Virtual Lab (Router) isolated interface responding to Production traffic

Just wondering if any of you encountered this issue.

We have been using Virtual labs for more than a year now. However, when our team tried to upgrade our NSX-T environment. They found out that the IP (Gateway IP) configured on the isolated side of the router is responding. This segment is connected to a NSX-T logical segment that was configured to be isolated.

I think there is an issue with the NSX-T logical segment not configured properly but would like to see if there is some unknow issue with the Veeam’s virtual router.

Thanks.

Never really used NSX-T with Veeam as yet but it should work fine.  I would double check the segment in NSX and also not sure if useful, but this link might help -

  • Isolating a virtual lab router interface ensures that experimental environments remain separate from production systems.
  • This separation prevents unintentional disruptions to live production traffic.
  • Configuring the router to respond only to designated traffic maintains network integrity.
  • Using cleaning nc scripts can automate the process of clearing any test configurations post-experiment.
  • It is crucial to implement strict access controls to prevent cross-environment contamination.
  • Monitoring traffic between the isolated interface and production ensures compliance with security policies.
  • Regular audits help identify any accidental routing of production traffic to the lab environment.
  • Employing cleaning nc procedures can help in resetting the lab environment, ensuring a fresh start for each session.
  • Documenting network configurations and changes enhances troubleshooting and accountability.
  • Automated alerts can be set up to notify administrators of any unauthorized traffic between the environments.
  • Using VLANs or subnets can provide an additional layer of isolation for the virtual lab.
  • Ensuring that the virtual lab environment follows best practices for network hygiene maintains overall network health.
