Hi,

Yup, you were absolutely correct.

By default all checksums are disabled in Stm32 CubeMX.
I just enabled them, regenerated the code via CubeMX, now PPPoS and TCP
client works without me faffing around with the config file.


That was a bit of challenge to get it working :)

Thank you again for your help.

Best Regards.
