Issue accessing work VPN

[Michellebo]

I work from home and need to connect to my work VPN which is Cisco AnyConnect VPN Client. It worked fine up until 11th September. Since then when i try and connect my work VPN i get the following message

The VPN connection to the selected gatewasy requires a routable IPv4 adapter address. Please move to an IPv4 network and retry the connection or select a different secure gateway.

Please can you help.

@Michellebo 

Are you using a white Max Hub?

@Michellebo .If you have a white Sky hub there could be an issue as by default Sky use a system to share IP4 addresses which can cause issues with some company VPNs there is a pinned post at the top of thecgorum explaing what to do if you are affected

I am using the black hub

[Chrisee]

@Michellebo in which case you have a standard dual stack connection with a IP4 addressing and a IP6 address and as far as we know Sky have made no changes to the set up which could cause your issue. Therefore apart from rebooting the hub which is always a good dtep the issue lies elsewhere.

I logged into the router and disabled IPv6 and the Cisco VPN client now works.

@Michellebo You may wish to get your IT people to look at the cisco client, as what you have done is NOT the right way to correct your issue!
