Hello! I have a problem with "hairpinning" with my Swisscom InternetBox. It used to work sometime last week but then it stopped. Here is what happens: \- LAN IP address: works \- Public IP address from outside the network: works \- Public IP address from inside the network: ERROR This is usually a problem with hairpinning from the router side and it seems that a new version of the firmware might have been released. Is there any way for me to either get a version where this still works or to fix it? Thanks!

Hi, Works for me just like usual. Have you contacted The Servicedesk already? [upl-image-preview liId=35125i7809E379C8F9174F alt=Screenshot_20191124_144946.jpg uuid=bee00db1-019c-4c35-aa57-1ad8178df26c] [upl-image-preview liId=35126iC3EE32AD08B29E86 alt=Screenshot_20191124_145234_com.android.chrome.jpg uuid=0d8034b3-2559-4062-a009-568381a73562] Have you checked your configuration or did you activated DMZ or Spanning Tree? Maybe it will solve your problems... Greetings, Dominik

"Hairpinning" not working anymore on firmware: 10.03.36/10.03.48/01507

Xander

DMZ and Spanning Tree are not enabled.

Only thing that I tried to enable was the DyDNS `xxxx.internet-box.ch` but that is not solving anything.

I tried reinstalling the FW and nothing changed. What else could I try?

Xander

P.S. can you try with a port which is not 80?

Xander

Also other Ports working for me, also notspecified Ports. Tested it with custom Port 85 for Cloud-Service and 32400 for Plex.

Can you try to reenable DMZ and Spanning Tree?

Otherwise i would suggest you to create a Backup and reset your Internet-Box. Try it again with just one Port e.g. 32400 or 90 and 80...

Greetings,

Dominik

Xander

I have just reset the box to factory settings and restoring the save cfg. Let's see.

I will then try to enable/disable the DMZ and TSP.

Otherwise, is there a way to install the previous FWs?

Xander

Ok, nothing changed... What next?

I really think it's firmware related at this point.

DomiP

I have found a Beta Version of the Internet-Box Firmware. I dont really know how it will work and if its better, but to get another Firmware you can try this oder contact the Service Desk at 0800 800 800 - maybe they can install you an older version.

Beta Version: https://www.swisscom.ch/de/privatkunden/hilfe/internet/firmware-aktualisierungen-fuer-ihre-internet-box/popup-firmware1.html#T=3d8c2af1-f30e-451a-9132-0b164673831c&TS=_NGUFl6ubCQtbj6ivnTa7qyhEQgYrETt0wO86uaUL6M

Xander

It says "wrong firmware file", I guess it doesn't work 😕

DomiP

Then, i would suggest you to Contact Hotline at 0800800800 and ask for help. If the 'first responder' couldnt help, ask for 2nd Level Support - they should solve it for you.

Very sorry, that the Restoring Process and the Beta didnt worked for you.

Hope, youll have a good solution soon.

Greetings,

Dominik

Hi Xander,

It worked for Years. But since about a week i got the exact same problem. Did you find a solution?

Cheers

EDIT: There are other threads on this issue.

(TLDR: We have to wait for next Firmware Release. Workaround: Own DNS Server. I don't like this workaround but it works perfect here.)

@DrFurunkel my workaround is MUCH easier than running your own DNS server: I use the DynDNS service and add that + local ip address in my `hosts` file. Done 😉

It works only locally but at least it works for now!

DomiP

Hi all,

i have heard, that they want to release the new Firmware very soon - so you shouldnt wait too long...

Greetings

DrFurunkel

@Xander Are you serious? Editing HOSTS.txt on every! client including Android/iOS is definitly not a solution. And you have to revert this in case you leave the house with Mobiles/Laptop.

DomiP

@DrFurunkel he did this action only so that he can use his normal systems until the bug was fixed. It is not a persistent solution.

My Internet Box 2 was updated to the new firmware version 10.04.02/10.04.00 on november 15. Up to now the IB2 runs perfectly.

It seems that only the IBP and the IBS are affected by this bug. It could be that there is a solution available soon. Do not know yet if we will rollout the new firmware or if we share it only on our homepage.

@antric Some customers have got a 10.4 Build. It is nearly the same as 10.3.36 but with a few adjustments. It's a mistake but because the build is as stable as 10.3 we do not downgrade theses boxes.
