Disable MAP-T

Can I request MAP-T to be disabled please. I cannot connect to my work VPN and they have advised it is related to Sky and MAP-T

@SDJ82 before a request can be escalated please explain which application is not working and confirming you have a white Sky hubs.

I have a white Sky Max Hub

I cannot access anything requiring access to the VPN, it is not a specific application, it is anything. Network shares, internal web pages etc...

Resolved this with the help of Sky Support

Went into Router settings then Gateway>Connection>Local IP Network and untick 'IPv6 Enable', click 'SAVE SETTINGS'

I was connected via Ethernet so unplugged the cable and plugged back in, connected to VPN and could access everything again

Hi @SDJ82

Glad that Support were able to help you work around the VPN issue.

Disabling IPv6 entirely isn't ideal, and in fact will force all your traffic to be translated and go over MAP-T. So at least we know your VPN issue isn't related to MAP-T, but it does sound like your VPN configuration has some IPv6-related interoperability issues instead.

Would you be willing to re-enable IPv6 to do a bit more diagnostics, and disable Unique Local Addresses (ULA) instead, a specific type of IPv6 addressing. In the past we've seen applications and services get a bit confused when presented with ULA, which isn't strictly required for normal IPv6 operations so can safely be disabled whilst still leaving IPv6 itself enabled; I'd love to hear if this alternative approach resolves the issue.

IPv6 Enable ticked, ULA Enable unticked = VPN does not work

IPv6 Enable unticked = VPN works

Thanks for taking the time to check that; it seems like there is some fundamental interoperability issue with your company's VPN and IPv6 in general.

If you don't mind feeding that back to them so that they can update their internal guidance around suggesting MAP-T is disable, and let them know I'd be happy to work with them on further diagnosing what the problem might be, if they'd like to reach out.

Thanks again for the extra help.
