Hi everyone,

Could anybody please tell me how this should be interpreted? I'm quite unsure how to setup port forwarding on router due to different name definition given by synology and by huawey router.

Internal port - external port - local port - router port

Synology external access

I assume I have to set these ports in my router, but is it really necessary to set these ports on my router providing the connection tests above are all ok?
If yes, how to enter the ports in the right field, 'cause a little confused what really is meant with "router port" and "local port" from synology point of view comparing to router´s "internal port" and "external port" from Huawey point of view. I think it is:

Router port = external port
Local port = internal port

PS. Documentation from Huawey is not helpful, the router is provided from ISP, capped at lot by the way.

Huawei external port is the port that is responding to outside traffic requests and then redirecting them to internal port. Internal in this case is the port expected and listening on your LAN side.

Router port = external port
Local port = internal port
This is correct mapping.

Looking at the Huawei screenshot: there are three fields tagged with *. Is there a footnote or other additional information to say that these are the mandatory fields? Because they are the minimum that you need to define a port forwarding rule:
  • Internal Host: that LAN IP where the inbound connection will be forwarded to.
  • Protocol (it's already pre-selected): TCP; UDP; TCP & UDP.
  • Internal port number: the port or range of ports on the destination host (the packet's new destination port).
  • External port number: the port or range of ports on the router (the original packet's destination port).
Internal port number can be the same as the External port number or be changed to a new number, depending on what port the Internal Host is using.

The other External Source IP/Port fields look to be additional parameters that can be used to restrict the port forwarding to specific initiating devices.

Just make it like the below and it should work. Of course, use your own port numbers and choose the protocol accordingly (TCP/UDP/both).

Thanks for added info. I just filled them out but doesn't work at all. See new post added about it.

Ok, but the question remains: why do I have to add these ports into the router if the connection test are indicated with OK -- as seen at the first screenshot? (Thus, assuming that it works even without the ports mapped in the router?!?).

It doesn't work for me. See new post.

I do enter the port as suggested and it doesn´t work. Popup a message like

after setting ports as follows:

Can you link to the Huawei documentation for your router.

Edit: did a search for this huawei "the configured port conflicts with the internal service port" and a few results and these specifically from TalkTalk users that are having problems with a Wifi Hub

According to @fredbert links above, it seems that this is an issue with a particular model.
What’s the model number of the one you’re using?

Does it work if you steer away from 80 and 443? Did you try that?

The model is Huawei EchoLife HG8247H. Steer away like what?

I don't know what they do mean by "wifi hub".

It looks like the device is under the impression that these are reserved for its own use. So what happens if you try to forward 30487 to 443, if does not allow it, try 30487 to DSM on 30487 for example (just different port numbers that are not used by services). Does it allow it? I know this is not what you want, but we’re trying to understand your device’s logic (if it has any).

Here’s the user guides page. However, it needs an ID and a password to download. Register and check the configuration guide and the FAQ/troubleshooting too. You might find something there.

You didn't give any indication on the actual model of device you own so I did a google search of the error message, being the only thing to do that might also reveal your device. The TalkTalk forum matched this search and they were discussing the WiFi Hub: which I assume is a name of a device provided by TalkTalk.

If I did understand what you meant by "30487 to 443, if does not allow it, try 30487 to DSM on 30487", no warnings was given by entering this:
1602955744938.png

But this port 30487 isn't requested by synology. But the question still remains: why do I need to enter the ports into the router if the connection is OK and synology requests to enter these port numbers into router?

I did register myself to huawei site, as indicated in your link, but couldn't have enough privileges to download the router's manual. So I did have to register a product to gain privileges. But again, it wasn't enough, I have to wait approval from them. But sincerely I skeptic it will be approved, 'cause the router wasn't acquired by me, it is a acquisition or contract from my ISP.

You can configure DSM to utilize this port (or many other free ports). But let’s understand what are you trying to do first.

But the question still remains: why do I need to enter the ports into the router if the connection is OK and synology requests to enter these port numbers into router?
You forward ports on the router so the connection request coming from WAN (external) to your LAN (internal) is not blocked. In other words, to allow external access.
If you’re saying the connection is OK then why are you bothered with all this, what are you trying to accomplish?

BTW, under “WAN Name” drop down list (your screenshot above showing “internet”), do you have any other options, can you click the drop down box?
