Port forwarding not findable on Huawei 5G CPE 3 routher

[euro234]

Hello! I am having problems finding port forwarding settings on my routher. Software version 11.0.5.51(H140SP2C418).

Couldn't find any help online.

I have no experience with 5G routers but some routers don't give you access to any custom controls.

Cellular connections are typically behind CGNAT and are not able to accept any incoming connections.

Welcome to the forums!
If Kilrah is correct, you'll have to talk to your carrier and see if they can give you a static IP. If they can, you may need an independant router to go with it.

I had a LMT & mikrotik partnership (which are both from my country lol) routher which could port forward. I don't see this as a ISP problem.

If the ISP does CGNAT then port forwarding does jack shit. Because you're still under another layer of NAT.

Well, ask the source, your ISP.

 

If you look up your WAN IP address and notice it’s in the 100.64.0.0 - 100.127.255.255 range, then you’re behind CGNAT.

My ISP Doesen't have any info about that on their site, but here's the info

Then you're behind CG-NAT, you're not going to be able to port forward.

I'd be curious if devices are directly contactable over IPv6 though, no port forwarding required.

 

I think most routers will block direct incoming connections though even on IPv6, but there may be a setting to change that but still problematic if the IPv6 allocation is not fixed.  That's a problem I ran into on the Xbox even on pfSense.

 

On the CPE Pro 2 the related settings are in Advanced, Security and I'd expect the Pro 3 to be the same, if those options are enabled on your firmware.  I'm seeing Firewall, MAC Address Filter, IP Filter, Virtual Server (Port Forwarding), Special Applications (Port Triggering), DMZ Settings, SIP ALG Settings, uPnP Settings (Automatic port forwarding/triggering), NAT Settings and Domain Filter.

I think IP Filter is what allows you enable specific ports to connect to IPv6 public addresses.  Its kinda like port forwarding except you aren't actually forwarding, you're just enabling the traffic to route normally to that port as IPv6 is already a public IP address.

Of course this is not ideal given what you want to use it for might be IPv4 only.
