I have 3 ip addresses I am trying to bridge across 2 ports on a cloudcore mikrotik router using winbox.
I have a /3 to get out to the internet. I have /24 public block for business use. Then I have a /20 private block for my subscribers. I need to be able to see traffic moving through my network across these ip blocks. I imagine it is relatively simple to set this up if you know what youre doing.

hi,

You have 3 different subnets that you are tying to put into a single Mikrotik ClouldCore Router.
1. to connect to internet should be /30 subnet (not /3 as mentioned). this is normally point to point to your ISP
2. /24 is your static public IP address-es, normally assign by your ISP.
3. /20 is your local private IP range that you would like to use to your subscribers(?)

to connect 1 and 2, you can do a simple Routing, not bridging and to connect 3, you will need NAT (with MASQ):
on mikrotik : /ip firewall

regards,

Yes I meant a /30. I currently have it configure with eth2 = /30 and either3 = /20 with the /24 masq. However I cannot see how the traffic is forming with this configuration. I know there is a way to BRIDGE these 3 ips across 2 ports without needing 2 routers. That is the reason I purchased the mikrotik over other brands. I also want to be able to assign VLANs to give the public ips to people that require them and use the private local ips for everyone else. THis is not possible with the current configuration.
