Mk As Bridge can't forward broadcast (DHCP one specifically)

RouterOS General
1

Hello everyone,

I use a RB750 as bridge.Only two interfaces are used as ports for a bridge interface.

My lan faces one port
My ISP faces the second one.

The bridge firewall option is not activated.
The problem is that one, from LAN side, with my pc configured dinamically, I can’t receive any dhcp response from ISP side.
However If i configure my pc statically, I can reach outside (internet).

I really need to work configured dynamically. How to fix that.

Thanks in advance.

Two ports in a simple bridge configuration will forward broadcasts. Something else is going on.

You could attempt to enable a DHCP client on the bridge interface as a test to see if the routerboard can get an address from your ISP.

You were right.
I did some additionals tricks and obscurs configurations that has falsified my test.

Thanks, and sorry for that noisy post :wink:
