unable to forward external port 8443 to internal 443

alcesmalchis — Sat, 22 Apr 2023 11:08:53 GMT

I have just upgraded to full fibre, with the TalkTalk Wi-Fi Hub 2, version SG4K100158, and am trying to reestablish the port forwarding i used with the previous router.

In the router GUI, i navigated to home / manage my devices / manage advanced settings, then selected the host i want to forward to from the list of wired ethernet devices.

On the device page, i selected the port forwarding / add rule tab and entered:

custom service name: nextcloud
service type: other (HTTPS forces both internal & external ports to 443)
protocol: TCP
external host: (left blank)
external port: 8443
internal port: 443

On selecting Add,I get the message "Operation could not complete, something wrong happened."

I also repeated the above with service type: HTTPS, which makes
both ports 443, with the same error message.

Notes:
1) I dont want to change the external port, as that would mean updating all my devices that sync to nextcloud!
2) I have changed the router address to 192.168.0.1
3) I have disabled the router's DHCP server, as I have one on my network already.
4) My local DHCP server uses dnsmasq, so also does DNS duty for the LAN.

can anyone help?

I also tried different ports, e.g. 10443 -> 9443, and external host * instead of blank, with the same result.

That error is normally with the Hub 1 (Sagemcom FAST 5364) when it runs version 3.00 hardware, but I have not found this on the Hub 2 at all. What hardware revision is this running & I will test it out after I hear back from you.

Mine is the same hardware revision, so I will try & test it tomorrow afternoon.

Hi @alcesmalchis

I have just set this up & it worked the first time:-

PF rule

Testing via a port checking website:-

Tested 8443 with port 443 open on PC

I did not get the "Operation could not complete, something wrong happened." error at all. I am running later firmware that is under test, but I never saw this error ever in V158 either. What happens if you do a factory reset of the Hub 2's configuration, does that get rid of the error?

I will give that a try when I return home; I am away for work until next Friday.

OK, I think that did it! The steps I followed were:

1) reset the router to factory defaults

2) login to router on 192.168.1.1

3) Attempt to setup the required port forward to 192.168.1.11 - accepted

4) Change router address to 192.168.0.1 with DHCP pool changed accordingly.

5) Reboot router & login again.

6) Change port forward to 192.168.0.11 - accepted

7) DISABLE router's DHCP server and power up my own.

😎 Restart my nextcloud server to pick up address 192.168.0.11

9) Check that my phone can now sync to nextcloud using the forwarded port - SUCCESS!

Incidentally, this also fixed a problem I was having with only being able to select DynDns as dynamic DNS provider - originally no others were listed, but now they are.

Thank you for your help Keith.
