No internet connection CRS326 + 2 RB4011

I am attempting to connect my ISP modem to a crs326-24g-2s+rm switch running SwOS.

My devices connect to that by connecting to a RB4011iGS+5HacQ2HnD-IN. There are in total 2 routers connected to the parent switch.

One of the routers is already receiving connection on WAN and it was as simple as plug and play.

The other router does not receive a connection. I’ve tried to duplicate the configuration of the other router and run that. same result. No internet.

Is there some limitation of this switch that prevents having more than one live connection to WAN?

No, it must be something else. Did you use /system backup save on one 4011, copy the file to the other one, and use /system backup restore there? If so, you have cloned the MAC addresses, so no wonder only one router works at a time.

I actually used the export import feature, would that still clone it?

export an import would not, so the issue is something else. The easiest way to describe the configurations is to post exports from all three devices, see my automatic signature for obfuscation hints.
