Details
You are using VMware NSX IDPS.You have a VMware NSX load balancer deployed.You have applied IDPS rules in Detect Only or Detect and Prevent mode under IDS/IPS & Malware Prevention - Gateway Rules - Gateway Specific Rules - <Tier 1 Logical Router>.There are IDPS rules applied to a VMware NSX Tier 1 Logical Router.This VMware NSX Tier 1 Logical Router has a VMware NSX load balancer configured on it.SSH and SCP traffic destined to the VMware NSX load balancer VIP do not work.When the IDPS rule applied to the VMware NSX Tier 1 is disabled, SSH and SCP traffic flows again.
Solution
Configuring IDPS in either Detect Only or Detect and Enforce mode on a VMware NSX Tier 1 logical router configured with a VMware NSX load balancer is not a supported configuration.Do not apply IDPS rules to a VMware NSX Tier 1 logical router which has a VMware NSX load balancer configured.
