Hi,
I've been having some random hung issue with my netduma r2, I've updated to the latest fw already (3.3.280) and had done the hard reset after fw upgrade to get a clean slate, but currently still will get the hung issue within couple of days of use, when the hung happened all internet traffic for all devices are stopped, I can't even access the router admin page (77.1) even if pc is directly connected through ethernet to the r2 ethernet port so I can't really retrieve any logs for debug, once I power cycled the r2 the internet access will come back but this is very frustrating, I have static ips assigned in my config and have already limit the range of DHCP assignments to above .100 and the reserved ip to be <100 according to one post and have maxed out the dhcp lease time didn't help with hung issue.
