Ubiquiti Cluster & rb750 setup

colorsnet · November 26, 2009, 5:34am

I have an adsl line coming into the rb750 and I have 4 nanostations on the other 4 ports. I need to setup each port on the rb750 to hand out ips from each dhcp server on the interface. So that I know which AP a client is on if they have problems.

I can only seem to get the first ap working on the rb750. It has dhcp server enabled and passing traffic and has active clients on it, but I can’t get the other 3 ports to work, even setting them up the same except for the ip address and dhcp range that i need.

Can anyone try and help me with this? I’m using 4.3 ROS…

thanks

Did you remove the default configuration and start from scratch or build on it?

Because the default config slaves ethernet ports 3, 4, and 5 to port 2. You need to remove that from the configuration to use them independently.

I did keep the default config, and built on it. But the master ports, I changed all of them to NONE. But you know what, I didn’t try the setup after I changed that… what a big dummy… Let me try that later on today and we’ll see. Thanks ROC…

Quick questios. On your adsl line are you using a pbublic or private IP. Also you want a seperate dhcp scheme for each of the ports that you have your Ubiquitis connected to. Is this correct? I have this working already and I will send you a script that should work with some minor modifications. Its Thanksgiving and I am feeling thankful.

Here is working configuration in my lab

; RB750
; Remove default configuration
; Winbox open new termial on left side of screen
; /system reset-config
; RB750 should reboot. Log back in using winbox. Ensure PC is plugged into Ethernet port 2
; Open terminal and it will ask to remove default config. Answer yes
; Assumption: Ethernet Port 1 will using a static public IP to backbone
;             Ethernet port 2 -5 NAT 
; Use DHCP pool range xxx.xxx.xxx.25 - xxx.xxx.xxx.200
; Maybe use static IP for Ubiquiti LAN and WLAN??? Not sure AP router or bridge

DSL is public ip but dynamic… Yes, COW you are correct, separate scheme for each eth port for each wireless ap connected to it… I will try your script here shortly and let you know later how it works for me. Thanks for taking the time to assist… I must have had it right because I read over your “notes” and I did exactly what you wrote to do, but as I stated in my previous post, I still had ports 3, 4 and 5 slaved to 2 and I removed that and didn’t test it afterwards… lol

will try here shortly, thanks again…

cowrv39 · November 27, 2009, 3:04pm

You are welcome. I will add to the script to ensure the switch ports are not set to slave.
I updated the script for dhcp client on ether1 and the default route change.

thanks again…

I did set this up “your way” and I did have everything setup correctly, except, I forgot to mention that I have hotspot setup on each interface in case someone tries to connect to one of the ap’s, and I can’t get the hotspot to pass traffic via eth1 (gateway port) from either of the other 4 ports..

When trying to login via the hotspot I get an error, no ip available from pool. And I used everything in your script and then setup the hotspot on my own for each port…

ever seen this before?
