Cisco Any Connect MTU problem

[sinisa1989]

Dakle, koristim Cisco Any Connect Secure Mobility Client (3.1.13015). Kad sam spojen na internet preko routera u uredu ili preko mobilnog hotspota, sve radi kako treba. Međutim, dok se pokušavam spojiti doma, nakon 1-2 minute mi izbaci poruku:

The client's MTU configuration sent from the secure gateway is too small. A value of at least 1280 is required in order to tunnel IPv6 traffic. Please contact your network administrator.

Probao sam par "popularnih" rješenja koje mi je google ponudio, no nijedno nije riješilo problem?
Router koji imam doma je Huawei HA35 (T-Com).
Ima netko ideju?

EDIT: Napravio sam reinstall, ponovno probao prvo rješenje i ispada da radi

You may get this error when you are trying to use the software VPN on an IPv6 network. The software will work on these networks, but you must use the IPv4 protocol settings and disable IPv6. This issue primarily affects Windows users.
Follow these steps to turn off IPv6 protocol in the Cisco Anyconnect VPN client.


1. Select the Start button and then select the Control Panel.
2. Under the Network and Internet category, select the Network and Sharing Center.
3. In the left-hand panel select Change Adapter Settings.
4. Right click on the "Cisco AnyConnect Secure Mobility Client Connection" and select "Properties"
5. Uncheck the "Internet Protocol Version 6 (TCP/IP v6)" box and click OK.
