Last time, you have recommended to use a URL dedicated to the SSTP service for the sake of clarity and understanding. Also, a VPN address "sstp.yourdomain.com" is not the worst kind. Warning to tell your DNS server an alias to your VPN server that is not necessarily the FQDN. Now I want to know about changing server certificate. Since, you guys have told me about the previous installation that helped me much, so I thought to post here my query instead of searching it on Internet. Please tell me in details about changing server certificate. Any other information related to the topic would be grateful.
