Hello, I have an issue with VPN trying establish connection but the funny thing is it worked before now probably after couple updates it crashes. Updated to v6.47

Log says:

TCP Connection established from <ip_address>

I added both rules in Filter accepting 1723 and GRE.
I have nothing in "active connection".
Port PPTP enabled but can't set the port nr it highlighted on red when trying set the port.

What else should I consider?
