Locked out of mu Mikrotik 450g

RouterOS Beginner Basics

I was doing some firewall set up and accidentally locked myself out. I will reset and upgrade to OS 6.6 again. However,

I wanted to know whether it’s possible to apply the same firewall rules to two different Ethernet ports if I don’t want to
use the address list. I had an Apple Extreme on Eth2 for my personal network and a Linksys wireless access point for my guess.
I tried to set up firewall rules that would apply to both device but could not find the IP address that the Mikrotik assigned each
device through the Interface panel. I realized that I didn’t want to assign a static address to each device…a dynamic one instead.

So, I decided I want the Mikrotik assigning IP addresses to both device so I can apply the same firewall rules to both device and to
not have more than nine rules. What should I do in the forward chain?

Thanks in advance!

If I right understood…
We have 3 ethernet ports:

  1. eth1-“wan”
  2. eth2-“lan1”
  3. eth3-“lan2”
    We need to use 1 “forward” rule for two lan intefaces:
    add chain=forward action=accept in-interface=!wan
