unRAID's internet access intermittent, while VMs on same nic are fine

[Davin S]

I originally posted in the Dockers section, have since realised this problem is affecting unRAID itself.

 

unRAID's internet connectivity drops in and out (LAN access is fine).  From command line, pinging any host on the internet, it flaps between normal ping times, and host unreachable.

 

VM's work perfectly the entire time, even when unRAID itself can't access the internet, and they're all using the same ethernet connection in bridge mode.

 

Docker UI access was intermittantly broken too when being NATed through to unRAID's 172.17.9.0 network, but have worked fine just like the VM's once they're given a custom network connection on the main /24 subnet.

 

I had a daul NIC card as well as the onboard, so took out the dual nic, but no change.  Added it back in with internet available on both ports, no change. 

 

What might be broken in Linux/unRAID host, that could still allow VM and Docker guests to work?
