Port Forward does not work..
-
@root1ng you can do it either way.. But with something like this you could have a problem.. But if your hitting the wan IP from the inside and not seeing traffic being sent on - that would be due to no nat reflection setup.
You might have to do a full proxy setup - not really a fan of nat reflection, its an abomination if you ask me ;)
But problem is even if you reflect if the source IP is local to where your sending it, and that something answers directly back.. The client might say hey wait a minute - I sent this traffic to mac abc (its gateway) why is mac xyz answering me.. You can see this very easy with dns and redirection.. There are plenty of posts around here going over that specific scenario..
But that really has nothing to do with plex doing the job of the port forward, but if you want plex to send the traffic to 1.6 when you hit your public IP from the lan side, that would need a nat reflection to be setup.

Ok, and do I enable nat reflection in Firewall - NAT - Port Forward for each rule added for the teamspeak server, or do I enable it globally from System > Advanced > Nat Reflection for Port Forward?
I think it's the same thing, but it's better to ask than to do another stupid thing :))
-
@root1ng I made some edits about nat reflection on my previous post, but you can set it up when you do the forward.

Ok and how do I do these settings? What should be set exactly? I don't understand, Pure NAT or NAT + Proxy or are there more advanced settings that need to be done?

I think I solved it and I hope I did the right thing, I changed the global settings, I'm attaching a picture below, is it okay?
By the way, this is how I can connect with the public IP from LAN/WiFi.
Without those two checked boxes I can't connect. (1:1 and outbound)

But that's not good, I connect and my IP changes to 172.16.1.1 which is actually the pfSense gateway.
Connecting with the public ip or dns I am assigned 172.16.1.1, if I connect with 172.16.1.6 I am assigned 172.16.1.5, I did something wrong.. -

Yeah, this is what NAT reflection does and what it has to do if it is enabled to avoid asymmetric traffic.
if I connect with 172.16.1.6 I am assigned 172.16.1.5, I did something wrong.
This connection doesn't pass pfSense, so it can do nothing on it, and it's also not necessary.

And what do you recommend? Should I leave Reflection off and connect with my local IP and the rest with the public one?

@root1ng
I recommend nothing regarding this. I didn't follow the whole thread and hence I don't know, why @johnpoz recommend to enable it.
Does this make incoming teamspeak connections succeed?NAT reflection basically needed if you really need to access the public IP from inside the network and if you cannot use the FQDN with DNS host overrides for whatever reason.
I don't expect that there is any change on incoming forwarded connections.The generated hidden outbound NAT rules should only be applied on traffic from another local subnet.

Anyone outside my network can connect with the public IP, only I can't, but I don't mind connecting with the local one. I will stay like this for a while, it seems safer to me.

why @johnpoz recommend to enable it.
Because he stated its not working when hitting his public IP from inside his network - which of course it wouldn't unless you were doing nat reflection.
I personally think the function shouldn't even be available - its an abomination to all things networking ;) But if that is what he wants to do - it would never working hitting the public IP from the inside without nat reflection

I'd expect, that you would rather recommend to use a public FQDN with DNS host overrides to achieve this.
But yes, if this is not an option for what ever reason, we don't know, NAT reflection is the only way to achieve this. -
@viragomann I would much rather suggest use a fqdn yes.. But his problem was based on ip and not seeing it.. Which he never would without nat reflection.
I was just troubleshooting his problem - not suggesting how he should setup his network.
But completely agree with you - in my multiple statements that nat reflection is an abomination ;) you should hit the local IP be that with IP or with a fqdn that resolves to your local IP when your local vs the public.

That's the way I know you.
As I mentioned, I didn't read all posts and I missed the reason for doing NAT reflection.
