Hi
after some researrch the problem seems to be on several areas.
- With 6.44 the dhcp package is no longer optional and it seems that it cannot be fully disabled. At least on my side a pool (which i never configured) appeared and assigned strange IP numbers 0.0.0.x . → so i switched back 6.43.
- having RSTP on the bridge switched on seems to make issues. Symptom: you can login via winbox using the MAC address and work without issues. With the IP obviosuly doesnt work for DHCP as the bridge doesnt get an IP. If you configure a fixed IP the system gets under a huge load (CPU 100%) and you get dropped often. → Switch of RSTP and fast forward on the bridge. see also here: http://forum.mikrotik.com/t/dhcp-client-on-bridge-does-not-work/118470/1
So now the system seems to work..
Remark to this gentleman argueing that im living on a stone. Im not sure if you know my setup and the reason for it, but i doubt. And you even doesnt know what is the plan. So plese stay in your own circles and cry but dont annoy others.
