Hi
I've setup my EdgeRouter PoE two months ago, over all it's running smoothly, expect one issue. When I try to ping any device behind the EdgeRouter or the EdgeRouter itself, I get a high responce time every 10 seconds. Le'ts say a ping to a google nameserver takes around 14ms, but every 10 seconds it raises to around 250ms for a short time:

Any idea what this could be? I used PPPoE, DHCP and zone based firewall on this device.
