Sagemcom router port forwarding rules add failure

[vtan5]

Hi guys, I've just setup my sagemcom router and trying to add port forwarding rules.

However, I keep getting "Operation could not complete, something wrong happened.". I'm not too sure what's wrong with the setup, can you please advice?

My rules are as follows:

What have I done wrongly? Do I need to specify the external host?

Thanks

Hi @KeithFrench the hard reset took me awhile, no idea why the button keeps "moving" but manage to see the flashing orange light so all good.

I tried again on the port forwarding before changing the 192.168.1.1 to 192.168.8.1, and it works.

Then i delete that and tried again on the 192.168.8.*, it seems to work fine this time. Really weird why factory reset works.

Thanks for the help, port forwarding all working again!

Hi @vtan5 

There were problems with using different IP addresses on the router in older firmware. What version are you running? If it is 2816 or 130 you should be fine.

[KeithFrench]

That looks fine, try the factory default of the configuration.

Hello @KeithFrench  thanks for coming back to me, I've changed the followings:

And i've also set the range as follows:

This was done before this post.

Am i missing anything?

[KeithFrench]

No, I am not saying that at all. It is just that it wouldn't work if the router was still set to 192.168.1.1.

I have just tried TCP port 687 on my Sagemcom & it forwarded fine without errors and actually worked.

I would suggest that you reset the router to the factory default configuration.

When you changed the router's IP address, did you:-

1. Change the DNS address handed out by DHCP

2. Change the router’s IP address & DHCP IPv4 Pool Start & End ranges to match.

Hi @KeithFrench yeah, i changed the router to have IP of 192.168.8.1, the range will be 192.168.8.10 - 192.168.8.254 (all else equals, just the 3rd position being 8 instead of 1.

So you're saying it won't work if I were to change it to 192.168.8.1 ?

[KeithFrench]

Is your router's IP address changed from the default of 192.168.1.1, as your rule points to an IP address of 192.168.8.20?

Leave the external host address as *, which is a wildcard to say that any IP address on the internet has the ability to try & connect to your router.
