Questions about using NAT
-
Hello, All
I'll admit I only know enough to be dangerous to myself generally before I begin. I've been using computers since DOS was the preferred interface for consumers.
That said I am trying, apparently in vain, to complete a simple operation such as open a few ports on my PfSense machine.
Everything runs beautifully otherwise on the older machine I assembled to run our firewall however I have discovered that while I can open port 25565, a minecraft server port for the kids, I cannot open 27015 for another server for them. As it happens in fact, I can ONLY seem to open 25565 and no other port correctly.
What IU would like to ask for help with is; what am I missing? I have checked the NAT rules in comparison to the 25565 rule and there are zero differences, all redirecting to an aliased machine on one of two LANs. Yet when anyone tries to connect to anything aside from the minecraft server they simply time out. I can port check from an outside source and see that 25565 is open while none of the other ports are open.
Additionally machines on LAN2 cannot see those other game servers on LAN1.
I would very much like to know where I need to start looking to fix this issue, my patience is running thin at this point and my frustrations are high with this problem. I have been enjoying using the PfSense software so much to this point and so I am quite troubled by this.

@ehkart Have you gone through these yet?

@kom I haven't, exactly why I came here to ask where to even start. Thank you for suggesting that route, I'll dig through that list and post on whether or not I find success. Thanks again.

@kom As it happens I started at step one, describing deleting and starting fresh each offensive rule. I also ensured to add logging to the WAN firewall rule that is automatically generated. I'm not sure how that should've helped but it has seemingly solved the issue. I have yet to be able to try logging into the host from an actual outside source but so far the program used to log in has a browser method that seems to be different from connecting via LAN. Thank you again, I'll be leaning heavier into the documentation in the future.
