[SOLVED] Dhcp Server on Bridge with vlan doesn't work

RouterOS General
1

Hello,

I have two access point ( Ubiquiti ) with two SSID’s ( vlan10 and vlan20 ) , but when I configure dhcp server over these interfaces, it doesn’t work. I don’t know why, I even try to configurate dhcp server over vlan interface ( not bridge ) but it didn’t work. I attach you an image to understand what i’m trying to do.

Any help will be welcome. I’m stucked for many days.

Everything works OK when I use static IP, but when i request IP to dhcp server it doesn’t work

Thanks you in advance.

I ran into case of wireless clients not getting dhcp once. Everything worked if I set static ip on the wireless clients. I spent hours trying to figure out and finally went for factory reset of the access point and start all over. Then it worked. So, my advice, if you’re stuck; start all over again.

I did it two times, but always with same result.

It doesn’t​ work and I don’t know why. I tried to set an IP to each interface, bridge, vlan but no result.

Reset RouterOS to factory default. and DO EXACTLY SAME AS I DID. then WORKING

It is likely the problem will return, nearly the same thing plagued me for a while… In a post somewhere (I’d give credit if I remembered where), I read that changing the MTU of the VLAN to 1504 would solve the problem. It did…
