VPN Issues

[Simmo78]

cmd run as admin 

netsh interface ipv4 show subinterfaces

netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent

worked a treat!!  Obviously change Wi-Fi with what ever interface you have on your machine.

Managed to confirm actual maximum for MTU as 1452. 

[Simmo78]

I tried and failed to see if there are options for MTU on the SKY MAX router, is this something that can be set on the LAN side?  This will be an easier long term fix.  Also can this issue be fed through the channels for when people call in.  I've heard varied approaches from the SKY customer service representatives, up to and including letting someone out of their contract early to change their ISP!!!

My IT admin have logged in remotely today, in the command prompt typed this;

netsh interface ipv4 set subinterface "WiFi" mtu=1452 store=persistent

Apparantly, "This will allow for the encapsulation headers of 48 bytes that SKY are using for MAP-T etc." they said.

However, i dont fully understand this, but hopefully will help some others. Bottom line is im back on AT&T (with a load of work to catch up on).

My IT have also managed to get the VPN working again by:-

Fix to be applied.

need admin access to local machine to carry out the following.

netsh interface ipv4 show subinterfaces
netsh interface ipv4 set subinterface 'WiFi" mtu=1452 store=persistent'

This will allow for the encapsulation headers of 48 bytes that SKY are using for MAP-T etc.

I can see that others have also had the same experience & this worked.

Hi there, I called several times to Sky because I can not connect on websites with my work laptop. Can someone help please, I want to be opted out the IP sharing (Map-T/CGNAT) asap. I have also logged in complaint but you have closed it without information

I am having the same issue. MY VPN drops out straight after I have connected. I am new to SKY on only seem to be having this issue since joining. VPN was fine when I was with BT. Not impressed so far. If some one can please get in touch as I need this resolving ASAP.

Thanks Martin.
