For some reason my 2011 is assigning IP addresses from its dhcp pool to computers on the inside of my network. The RB2013 has a dhcp pool of 10.5.50.20-10.5.50.254 and the modem is 192.168.0.1. The router is not only forcing 10.5.50.xx addresses on computers that get an address from the modems dhpc, it also attempts to force the modem into its class A dhcp range to the point where everything has to be restarted and leaving the router disconnected or disabled the bridge.
The router gets its address from the modem by using dhcp client, and making it static does not help. I know I am overlooking something dumb and its most likely a switch, but I am at a loss so I am hoping someone here might have an idea. Needless to say, but I’m starting to feel really stupid and I have been using mikrotik routers for 7 years and never ran into this problem until now.
It sounds like some bridge ports are wrongly added.
My assumptions are:
You have a modem/router which is DHCP server on the 192.168.0.0 network, have several computers connected and also 1 port of the RouterBoard.
Behind the routerboard you have again several systems and routerboard is acting as DHCP server for the 10.5.5.0 network.
If the computers connected to the modem get IP’s from your routerboard the interface connected to the modem should be member of the bridge where the DHCP server is configured on.
Thanks for the help. It seems I caught a severe case of the dumb A$$ and I had the WAN port on the bridge which allowed the dhcp server to push addresses back onto the modem and inside computers. WOW, can’t believe I did that.
