Issue/Introduction
When internet traffic is routed direct, intermittent website access issues for users behind SDWAN edge
Environment
VMware Velocloud SDWAN Edge
Cause
Edge is taking longer period of time to create a NAT entry as NAT ports are mostly busy. Edge software version 4.5.2, 5.2.3.x, and 5.2.4.x are affected. This scenario happens often when end customers are using Proxy to send traffic.
Resolution
The issue is caused by incorrect information in the NAT table that tracks the available ports and the ports in use, the reason for incorrect information is known issues (#142997 and #144189) with HA port information sync between active and standby edges.
Dev has recommended a simultaneous reboot of both edges (active and standby) to clear the incorrect information in the NAT table.
These known issues (#142997 and #144189) are fixed in 6.0.0.1, 6.0.1.0, 6.1.0.0.
