Port-forwarding no working

ferdzo · September 19, 2024, 11:47am

I have a Mikrotik HAP AX lite as a main router on bridged Huawei fiber router. And I need to port-forward port 4368 and 4370. I have tried everything dstnat by myself, copying commands from the internet, even using the QuickSet Port Mapping feature which makes a dstnat rule again the same as I. The closest I was when I tried to also port forward telnet because the device I have also has telnet, and I got to the router’s telnet. There is some traffic on the rules couple of packets but then it’s just fails to connect. I tried everything even disabling the firewall rules. Can you help in anyway?
Here is the config:

Reading your firewall rules was making my head explode. Do yourself (and the rest of us) a favor and move your firewall rules around so that all the rules in each chain are together. In other words, all the Input chain, then all the forward chain, etc. Does not make any difference to the router, but makes it FAR easier for us poor humans to read.

Also (and this is my opinion - shared with a lot of others as well), change your rule strategy so that you have rules that specifically allow what you want to all, and then the last rule in each chain is a drop everything. You are running a combination of allow and drop rules intermixed which makes it more confusing, and far more prone to errors. In some situations you have to do some strange stuff, but the allow what you want and drop everything at the end works well for most situations.

With all that said, your problem description says that you want to forward ports 4367 and 4370, but your NAT rules are ports 4368 and 4370. Also port 4368 you are NATting UDP and TCP, but 4370 only UDP. Don’t know if either of those are part of your problem.

Thanks for the improvement insights, I will do it for sure. There’s an error in the text I want 4368 and 4370 ports open. Anyway I saw that 4368 is only TCP, but that is not the problem. I can’t access any of the ports on TCP nor UDP.
