we have configured a SpeedFusion VPN between two Peplink Balance 210 Routers last month.
The SpeedFusion VPN worked like a charm until a couple of days ago the customer started experiencing very poor data and voice communications performance and packet loss across the SpeedFusion VPN.
Based on what we have seen so far, it seems that only SpeedFusion VPN traffic is affected by packet loss, while Internet access is not affected on any side.
We don’t get the packet loss when continuously pinging all WANs’ public IP addresses from an external core router, so judging by that I would say the problem is on the SpeedFusion VPN rather than on the WAN connections themselves.
What would you suggest in order to more effectively test the actual transmission quality of each WAN link (e.g. increasing the continuous ping packet size, using specific monitoring tools etc.) ?
Any help would be greatly appreciated.
Thanks and Regards,
