Hi!

I’ve noticed that I can succesfully connect to my corporate VPN, but once connected I cannot work anymore: Any application connection, or web browser activity gets suddenly stopped once the VPN connection is stablished. This used to work fine, but apparently something got broken in the last days.

Thanks in advance for your support.

Hi, I have just switched to UPC and a VPN that worked fine with Sunrise and previously Swisscom no longer works. Seeing the older thread above…. any ideas please? Thank you 🙂

You should ask UPC if they activated IPv6 (through IPv4 tunneling).

This breaks a lot of VPN configuration.

Reverting to IPv4 solved the problem for me and many other on this forum.

Hello @Dorothythy,

With most VPNs setup, for security reasons, when you establish a connection to the remote network you will also use the internet gateway of the remote network. This is to make sure you go through de remote network firewall and network security.

The fact that you can’t access internet anymore may or may not be related to the change of box but in any case you have to address the support of the school first to pinpoint the exact problem as the network configuration when you are connected is dictated by them not UPC.

Hi @Icarus

The situation is I can connect to internet, but then when I connect to my school VPN through cisco Anyconnect (I assumed it is connected as it said), I cannot browse the webpage anymore, what is the problem and how should I fix it?

Thanks!

Hello @Dorothythy,

Just to make sure… what is a vpn for you?

Hi upc

I cannot access the internet once I connected to VPN. This is the first time I connect again to VPN after changing the upc box. Is this the reason? and how to solve it?

Thank you.

Dorothy

Hello, My VPN connection was working fine until around 12:30.

Around this time my internet connection was lost.

When service resumed I could no longer connect though my VPN.

If my service was “upgraded” to Ip-6 please revert ASAP.
I am not able to work.

The solution is the same as above. The explanation from my vpn provider is that my they only supports IPv4 which is incompatible with Dual-Stack Lite (DS-Lite) for IPv6 rolled out by cablecom. The solution is to call cablecom and have them switch you back to IPV4. Hope this helps.

Hi,

I have the same issue. VPN doesn’t work anymore also it used to work and it sill works if I use my Sunrise mobile connexion.

I already opened two Contact Us case with Cablecom, but they did not even answer.

Kohoumono, is your problem solved? How?

Thanks in advance.

Sorry to highjack thread, I am experiencing the same problems with my vpn. Do you think the same solution would work for me? Many thanks in advance.
