Unable to use OpenVPN

[kRel]

Good morning to all and well found This is my first msg, a request for help. I hope to write in the correct section.

For months, until last month, OpenVPN worked perfectly.

My internet provider Fastweb, which has always provided me with a static public IP, (with which OpenVPN has always worked perfectly) for a month, has connected the GPON fiber optic to my home and my public static IP has changed.

From that day, despite having updated the new static public IP in the OpenVPN configuration, I can no longer access the internet via OpenVPN.

I use OpenVPN via my Synology NAS (DS918+) with the configuration as shown in the image - configuration that has always worked well.

Even using the "Export Configuration" function and applying the configuration to other machines, the VPN connection no longer works.

Could you help me please?

Greetings.

This is my SynologyNAS OpenVPN configuration:

# The "float" tells OpenVPN to accept authenticated packets from any address,
# not only the address which was specified in the --remote option.
# This is useful when you are connecting to a peer which holds a dynamic address
# such as a dial-in user or DHCP client.
# (Please refer to the manual of OpenVPN for more information.)

#float

# If redirect-gateway is enabled, the client will redirect it's
# default network gateway through the VPN.
# It means the VPN connection will firstly connect to the VPN Server
# and then to the internet.
# (Please refer to the manual of OpenVPN for more information.)

#redirect-gateway def1

# dhcp-option DNS: To set primary domain name server address.
