I found a lot of complains about the Sagemcom Fast 5688W Gateway with VPN. I have the same problem. My firmware version is SGJi10202-1.2.74.

VPN does not work from my Windows PC, but it works with my iPhone and iPad!!!

I found out that it could have something to do with the MTU packet size. This MTU value can be changed under Windows. Until now I didn’t have time to dig into this. Does anyone know how to do it and tested this?

The firmware of the Sagemcom Fast 5688W Gateway is absolutely poor. I think everyone should contact T-Mobile and complain about this firmware. T-Mobile needs more pressure to enhance this black box.

I don’t know if anyone is still having the issue but ever since the latest upgrade my FAST5688W has been giving me issues with connecting to my Company’s VPN.

Same here. Took me a lot of time to figure it out.
