Can't connect to my work VPN. Routing error

I tried both from my phone AND DSL connection. The traceroute is sending the request through some weird places. Looks like ISP problem.

 

Buy a Fritzbox and all problems are solved

Which weird places?

That doesn’t make any sense. The problem happens with LTE as well.

 

The traceroute:

Which target adress you seek to get?

Hello @diegoeche and welcome to our o2 community :-)

There are a lot of things that may result in problems working with a VPN, but it should still work as long as the traffic reaches its destination.

I already wrote an eloquente answer, contacted an internal departement with a trace, did not send this answer , had a virtual meeting, came back to this page, thought that this is quite good since I already recieved an answer, refreshed and found that I did not answer in the first place. Well…

Okay, so forst of all, if you want to hide the traces that you made, just drop a short answer and I will happily do so.

The traces indeed look quite interesting, up to DE-CI in Frankfurt everything looks right, then off it goes to Korea, California, across the States and back to the East Coast.

That does not look quite alright, I guess a connection across the Atlantic would work better.

As mentioned before I informed an internal departement with the routing and I recieved an answer a short time later.

The technical departement raised a ticket against another departement that is responsible for the IP traffic and they will have a look into this as fast as possible.

Since there are many other possible reasons why a VOPN connection may fail please also keep on searching if there still may be a reason for this on your side or on the side of the companys VPN :-)

Thanks Lars.

Yes, I’d love if you delete those traces/domain names since I’m on a strict NDA policy.

So the crazy thing is that my company did check many VPNs and other remote workers have no problems. We tried the US/based one, the Netherlands-based one. And can’t connect always fails with a timeout. Can’t even access the server of the VPN through the browser (it timeouts). Doesn’t seem to be VPN but a network-layer issue in this case.

Thanks again for raising the issue, I’d appreciate any update.

Cheers,
Diego
 

Hello @diegoeche,

I deleted the traces. As soon as I recieve an update I will inform you :-)

I assume this will be tomorrow the earliest since my working hours just ran out…

Hello @diegoeche,

I just ran a traceroute and it seems like the routing is now working as it should. Please have a look at it and try if everything is working again :-)

Regards,

Lars

Hello Lars.

Thanks so much for your support. Everything is now working! :)

As a Software Engineer, gotta say I’m super curious! Any idea what happened?

Anyway, thanks again to you and your team!
