Dear all, was the Port Forwarding issue ever solved for the Wifi hub / Sagemcom Fast 5364?

I have spent a good day trying all sort of settings with no success at all.

 

I am trying open port 80 for http and port 3389 for Remote Desktop.

 

Thanks.

There has never been any issues with port forwarding on this router at all. What testing are you doing that fails. With RDP you may have to get Scam Protection disabled and you will definitely need to allow these connections through any personal firewalls on the devics that you are trying to forward to.

I have disabled Scam Protection but it makes no difference.

 

As well as RDP I am also trying to setup a webserver on port 80. Checking on port checkers show that the port is open, so it must be something about the way it forwards internally? The internal host address works fine inside the network.

 

This is the post I am refering to with similar issues. https://community.talktalk.co.uk/t5/Fibre-Broadband/Port-Forwarding-on-New-Sagemcom-Fast-5364-Issue/...

 

I attach the configuration - any help would be much appreciated! Thanks.Capture.JPG

Solution

If the port reports open, there is nothing wrong with the TalkTalk network, router or any firewall you may have on this machine or basic setup of the web server. How are you testing this, as I think you may be generating loopback traffic?

 

If you try to connect to the web server from a device locally connected to your router & try to connect to either the router's WAN IP address or DDNS domain, you are going out to the internet & back in again. This is classed as loopback traffic and all TalkTalk routers consider this a security risk & block such traffic. What you need to do is test from a phone that is disconnected from the Wi-Fi and is using 3/4G to connect to the web server, or try from a different internet connection such as another broadband link.

I was indeed testing from a machine locally connected to the router. However I have now tried from my phone and a different braodband connection and unfortunately it still says unable to connect. 

 

Any more hints or areas would be much appreciated!

First to save any confusion, assuming that the web server is running on a Windows pc, when you say that the port is open, you are using a site like:-

 

https://portchecker.co

 

and not simply netstat?

@KeithFrench I made the error of having the linux webserver switched off while testing it away from home.

 

I've now tried it on my mobile with the server running and it works!

As you rightly deduced it was due to loopback traffic.  Thanks again for your help. Don't think I would have ever worked this out by myself. :thumbsup:

Hi @basilbrush909 

 

If you want help, you cannot use someone else's thread.

To get help, you must start your own thread. To create your own thread, go to the main page for the board in question & click the "Start a topic" button.

TalkTalk insists on one thread per problem per customer. Please note, TalkTalk makes the rules, not me.

 

If you can list the TCP or UDP ports that you want to forward (I have no idea what steam is or the ports it uses), I will be able to not only tell how to complete the port forwarding configuration on the hub, but will be able to test it on my hub first. 

 

When you have created your thread with this information within it, please PM me with a link to it, so as I can find it easily.

Thanks.

Hi @basilbrush909 

 

I am more than happy to help you, but you did not start this thread, if you look at post #1 it was started by parachute_man who was asking about forwarding port 80 for http and port 3389 for Remote Desktop. Your enquiry is about a totally different set of ports.

I stated that I do not make the rules, TalkTalk do & it makes so much sense where potentially complex questions are posed. So please create your own thread & I reiterate:-

 

If you can list the TCP or UDP ports that you want to forward (I have no idea what steam is or the ports it uses), I will be able to not only tell how to complete the port forwarding configuration on the hub, but will be able to test it on my hub first. 

 

When you have created your thread with this information within it, please PM me with a link to it, so as I can find it easily.

 

I know there is a predefined forwarding rule for a stream client & server, but unless I know what ports these use, I cannot test it for you & help you to resolve your issues.
