XR500 with QNAP NAS Problem

[Wixell]

Hello Everyone,

I bought XR500 2 days ago and I found my QNAP NAS (TS-420) lost the connectivity to XR500 (wired, 1Gbps) intermittently until I reboot the XR500. Nothing special logged in the log file. Both hardware are using the latest firmware. Any ideas? Thanks a lot.

Untick 'Disable IGMP Proxying' in Settings > WAN Setup and see if that resolves the issue please.
