Just weird. After cleaning up my experiment, (removing all VLAN settings in the Omnitik as I could eliminate that node from my VLAN network) my home network failed every two or 3 days. The Draytek router crashed and reported “fraggle attack”. Just by accident while looking in the Omnitik sitting idle, just connected with ether1, I saw it’s DHCP lease go from offered-bounded-error. Never seen that error before. Nothing in the log. The config was cleaned back to default (except for ether1 on the bridge, DHCP server removed and DHCP client on the bridge). Reboot, 10 min power off, nothing helped. Ultimately had to reset the configuration, and make the same simple changes again. All clear, network stable , DHCP lease bound for 5 days.
This VLAN stuff seems not to be cleaning up everything, if just removed manually. Is it ? I have no explanation for the “fraggle attack” nor for the error of the DHCP leases. Don’t like hidden persistent parameters or configurations. ROS 6.47.4 related ???
