Remapping bridge to new ethernet interface

RouterOS Beginner Basics

Hello, dear Mikrotik connoisseurs. I have a question regarding changing a pre-existing bridge’s interface (physical LAN port). Below is the current interface setting of my RouterOS running on an x64 device.

#    NAME        TYPE       ACTUAL-MTU  L2MTU  MAC-ADDRESS      
0 R  ether1      ether            1500         ***
1 RS ether2      ether            1500         ***
2  S ether5      ether            1500         ***
3 R  bridge1     bridge           1500  65535  ***
4 R  lo          loopback        65536         00:00:00:00:00:00
5 R  pppoe-out1  pppoe-out        1492                          
6 R  vlan1       vlan             1500         ***

Currently, at /interface/bridge/port, ‘ether2’ is mapped to ‘bridge1’, and ‘ether5’ will be the new interface for ‘bridge1’. What I have tried out is simply changing the LAN interface of the bridge port or adding a new port (ether5) for ‘bridge1’. Both methods didn’t work, so after applying the changed/new port (interface) for ‘bridge1’ and re-plugging the local clients to ‘ether5’, the clients can get local IP addresses but don’t get the internet.

Could you advise me on this matter? Thanks, folks!

If you have a relatively default config you should be able to just add ether5 to the bridge and it would work. Access to the internet is usually controlled by interface-list “LAN”. Which interfaces are in that list?

If you need more info, post a full config.
