For my own curiosity and playing around with Windows Servers at home to save me changing IP address when the ISP updates I purchased a static IP via VPN provider. Also given it would be an IP only used by me, I should be able to send mail and receive mail as it shouldn't be an IP listed in any spam filters.
I have a router which support OpenVPN and have setup port forwarding for incoming connections to my server at home. But can't seem to get anything to be seen while using the VPN static IP.
If I turn off the VPN it works but due to having the ISP public IP address I cannot send mail to a lot of people.
Is there any way I can utilize this VPN purchased static IP for my Exchange Server at home?
My ISP does not provide static IP's otherwise I would have used them.
