I have set up the below as a test before installing equipment onto my tower. The laptop is simulating a Wiligear AP interface. The problem here is that my RB133c is not passing IP from the tower to the RB450. I know Layer 2 is good because from the laptop I can see other Mikrotik devices that are past the RB133c when using a MAC scan. Also, I can ping the RB450 and laptop from the RB133c and vice versa. I have the RB133c setup in station mode and created a bridge with wlan1 and ether1 ports. The RB450 also has a bridge containing ether1-3. The tower, both bridges, and the laptop are on the same subnet. Please help me out. Thanks,
Justin

My first and probably most obvious question is - where is your config? Simply telling us that everything is bridged does not really help… Pls post IP addresses and routes at the very least from your MT. Showing the interfaces with their config would be good too.
My first observation - why are you bridging everything? You should be using routing, static routing at the very least. Bridging has only a few instances where it needs to be used, mesh like networks, putting ‘resources’ on the same network that can’t be accomplished via a VPN or some other secure tunnel (very rare), and bringing disparate networks together. You may want to consider using routing - it’s much cleaner and easier to control that a bridged network.

I do agree that I need to be routing and this is a prelude to getting to that config. In order for me to communicate with devices already up and operational and not interrupt traffic I need to start with this bridged model and then reconfigure each device to be routed. Once I have this setup working and installed on the tower I will be immediately reconfiguring to a routed network. I’ll work on getting a config posted.
I no longer need a solution to this problem. I solved it with a routed/EoIP solution. Thanks.

A little better explanation of your solution would go a long way towards helping others when this type of issue arises… That what the forum is for…

You are correct. First, my situation: I am standing up a new tower site and had a 4 x radio AP + 3 2.4Ghz sectors and 1 5.8Ghz grid antennas mounted. Also I had a 2.4Ghz radio/antenna installed for backhaul. Well the backhaul radio failed while on the tower (Wiligear) and was taken down. This presented an opportunity to move to a Mikrotik device and start my transition from a bridged to a routed network. Since the 4x AP was still up there and not programmed for an IP conducive to my routed network I needed to communicate with it to change the IP once the Mikrotik devices get set up. All of my communication needs to come over the wireless link as the installers are not IP savvy and I need to remotely configure everything. Thus I was simply going to bridge the Mikrotik in the same way that the Wiligear backhaul radio was configured. It turns out that this was not possible with the Mikrotik and I needed to utilize a routed config on the Mikrotiks and built an EoIP tunnel from the NOC router to the AP facing interface on my RB450 which allowed me to bridge the NOC router subnet with the 4x AP subnet and reconfigure it’s IP address. See below diagram. Hopefully this will help someone else address a similar problem.
