Brigde configuration

RouterOS Beginner Basics
1

Hi,
I have a Mikrotik 750 with firmware version 5.4 and another Mikrotik 750G with updated firmware version 6.12
On my Mikrotik750 I have the configuration that I need working, but the same rules (I think that all is equal) don’t work with firmware version 6.12.

Attached I’m sending a image with the network schema.

What I need:

  • My internal machines can surf the internet;
  • The traffic with destination IP 200.132.0.1 must be redirected to internal machine with IP 192.168.0.1; (So I created a brigde with this IP and a NAT rule - dstnat)
  • The traffic with destination IP 200.132.0.2 must be redirected to internal machine with IP 192.168.0.2; (So I created a brigde with this IP and a NAT rule - dstnat)

What I have:

  • bridge-internal with IP 192.168.0.254 vinculated with the ethernet port1
  • bridge-external1 with IP 200.132.0.1 vinculated with the ethernet port2
  • bridge-external2 with IP 200.132.0.2 vinculated with the ethernet port3
  • NAT rule (dstnat) dst 200.132.0.1 port 80 redirect to 192.168.0.1 port 80
  • NAT rule (dstnat) dst 200.132.0.2 port 80 redirect to 192.168.0.2 port 80
  • NAT rule masquerade

In the firmware version 5.4 I don’t need to select a operation mode like router or bridge, but in 6.12 version I have this option, in my case what’s the right mode?

Thanks
