WDS and DHCP - Possible?

RouterOS General
1

Hello all, I am still new to this world so I hope I can explain myself correctly. I currently have a lab set up with three MT routerboards all running 2.18.6. My situation is this: All three are running WDS sucessfully. I can plug into any of my ether2 ports and ping all of the other enet ports on all radios. So I think that part is okay. My problem is this. In the real world I will need to have one of these sites run dhcp on one of the wlan interfaces. It doesn’t seem to do it though. I have gone to one of the MT boards, configured DHCP on of of the wlan interfaces (obviously using a different IP range than the WDS) and it accepts it. Some data:

wds1: ip address = 172.16.255.1/30
wlan: ip address = 10.1.1.1/24

The DHCp server says it is running and I can’t detect any problems. Now, when I plug in my wireless card or use a CPE to try and get an address from that particular AP, it won’t do it. Does anyone know of a reason for this. My only thought thus far is that the WDS interface thouroughly controls the wlan and won’t allow it to also function as a AP (i.e., for a hotspot). Am I just doing this wrong? Any help will be most appreciated. :astonished:

I thought that I would post a reply to this to help all the other poor folks. I never recieved any replies to my post but I did figure out how to do what I needed. Here are the steps necessary:

  1. Ensure that the IP address range you addd to the WDS interface is large enough (i.e., < 30) for instance 192.168.110.1/24 would work.

  2. Create a new bridge interface.

  3. Give your Wlan an IP address within the range of your WDS (i.e., 192.168.110.2/24).

  4. Configure the bridge you just created to bridge the Wlan and the WDS you just created.

  5. That’s it! Now you can set up your DHCP server or whatever you would normally do with the wlan interface.

I hope this helps others. And, if any of you knew this and didn’t answer: shame on you!
