forward eth ports to an external public IP

RouterOS Forwarding Protocols
1

I have a RB2011iL mikrotik router, and I want to forward eth connections to an external public IP, like this:

client → eth2 → publicIP

so I want to connect client with public IP.

I tried NAT Rule forwarding, but it doesn’t work.

Three options:

  1. Destination NAT
  2. Bridge ether2 to wan port
  3. If you have routed subnet then assign public IP address directly to the client (simple routing)

Thanks for reply.

Here are some examples

What is your config?

I don’t want to forward to local IP, I want to forward to external IP.

Simply set up masquerade on public port
