Port Forwarding not working

Hi All.

I'm having an issue with port forwarding.
Keeps showing blocked for any port I open.

I'm with Vumatel aerial and CI as my ISP.
Have the stock CI router - Archer C20.
No other routers on the network, only a range extender also TP-Link.

Any port I try is blocked, the only port I can get open is when I setup remote management, but that does not help as the port is then busy....

What I tried :
Different ports.
Different LAN static IPs.
Different Local PCs linked to the open ports. (3 PCs tested in total so far)
Port forward static IP set to the router itself.
Firewall off.
Firewall on with port rules set.
Firmware update on my router.
Factory reset on Router.
Different software needing an open port.
PPPoE changed to Dynamic (internet drops of course)

and I have contacted CI Support - no help, says they don't block ports. Great...
but I don't deal with routers everyday, so inform me what else I can try. I'm sure I'm not the only one in the CI Group with an issue like this???
- after a few hours today of more trying the same things in a different order I emailed support again and asked if Vuma can maybe do a reset or something? They came back and said yes, with a Ref number but have not heard from them again and the ports still don't forward.

I am now out of (Cool)-Ideas, I can't find anything else on the internet.

Did anyone else ever experienced this before? Share your (Smart)-Ideas with me please!!!
 
Hi, What port are you trying to open and why?

Is the device connected via the range extender or directly to the router?

But as mentioned by support there is no filtering from our side.

Any port. Its for PC's, not other devices.

Trying to get my Factorio and Minecraft Servers running again, used to host 4 of each for friends and family at my current location with all the same hardware and software.

I have tried the following ports.

2000
20194
25565
25560
34567

The ones I can remember off the top of my head.

So its not a device using a certain port. If I do a “netstat -ab” then my open ports do not show.

Check if you are being Double NAT'ed. If they have you behind a CGNAT your public IP (do a whatismyip test) and the 'public' IP on your router WAN port will differ

We don't double nat Vumatel aerial we have enough v4 as mentioned in our other posts.

Thanks for the reply.

Checked and the IPs are the same :(

So running that command will give you a report of listening ports on the device in question not really to do with how the outside world would get to that device. So maybe the service isn't running correctly?

I don't think the why is important here. Because he wants to is a good enough reason. Your response should rather be something like 'what are you trying to achieve?'

Well from a technical perspective it's better asking the basic questions and then leading to what wants to achieve. Often customers aren't actually sure what they want to achieve but know what they are trying to configure. But thanks for the opinion :)
 
Everytime I challenge you on the way you answer these posts you reply with something about customers being ignorant or worse. You really should learn how to interact with your customers. 2c more for free

How am I implying customers are ignorant with a series of questions that will help me to assist the customer?

I help people everyday on this forum.
 
AFAIK vumatel is dhcp by default, that aside, try using dmz and see what happens.

Not understanding the "service isn't running correctly" part.

So for a Minecraft or Factorio server, you need to explicitly assign a port in the server properties at start up, they can't use UPnP like a client game (Steam games)

So its not the "Service" if you meant the Game Server Software. I can make it which ever port I need it to be. In this case any open port.

I can ping my Public IP, I can ping my Dynamic DNS too. As soon as I try to access via any port then it shows blocked.

I'm used to having an error like connection refused, which means my port forward is not looking at the right local IP on my network.

Aerial is PPP, DMZ is basically removing all filtering which might not be great but not a bad way to test either way.

Dmz is definitely not a permanent solution but just to rule out firewall rule issues being the culprit.

Yeah so when you run the game server it should bind to an IP and port on the local device (server, PC etc) then the netstat command should show that port as listening on one of the interfaces.

Does it work across your lan?

Local Lan works perfectly fine, this will be hosted on your client side and not on your server side.

Server does not bind. Gives an error " **** FAILED TO BIND TO PORT! **** "

Just ran a telnet too, get this error " Connecting to 155.93.###.###. . . Could not open connection to the host, on port 25565: Connect failed "

Tried with all ports currently set as open.

I have also tried with different versions of my server files, all the versions which I have as backups and which ran perfectly before, all not binding.

Go under DHCP Server -> Address Reservation. Choose "Add New" then bind your PC's MAC to an IP within your DHCP range.

Then make sure the IP address in your port forwarding rules is set to the one you just reserved.

Then reboot your router and check if the forwarding works.
