Simple ISP VLAN on WAN-ether1 and OVPN/SSTP Server

Hi.
I have a RB951 with defaults: OS Level4 6.41.4, ether1->WAN, ether2->master, else slave of ether2 on bridge
1- My ISP provider gave me a router with Fiber GPON and sent me the configuration to put on Microtik:
1.1- Fixed IP :X.X.X.38
1.2- Gateway: X.X.X.36
1.3- DNS Servers: X.X.X.X, X.X.X.X
1.4-VLAN ID=20
2- I have setup the Microtik:
2.1- Added VLan on Ether1 with VLAN ID=20 with name “vlan20”
2.2- Added Adress on “vlan20”: X.X.X.38/30 , Network: X.X.X.36
2.3- Removed Adress from ether1
2.4 Added DNS Servers on IP->DNS
2.5 Added rule in IP->Firewall->NAT: Chain=srcnat, Out.Interface=vlan20, Action=srcnat

Internet/Network is working.
Then i decided to ativate OVPN/SSTP Server, using the same setup ( https://www.medo64.com/2016/12/simple-openvpn-server-on-mikrotik/) already working on several Microtik Routers.
I have the problem of not connecting (timeout) to the OVPN/SSTP server on the Microtik, and not even in the log appears the initial connection.
Is my initial setup donne correctly?
