  • Hi John,

     

    As far as I know, we cannot change PPTP and L2TP port number. However, for SSTP we can change VPN to listen on different port. Please modify the following registry key to change the port number:

     

    HKLM\System\CurrentControlSet\Services\Sstpsvc\Parameters\ListenerPort

     

    Note: The VPN client always connect to TCP port 443. Some device sitting in-front of VPN server (like ANT router, SSL load balancer) can change the port number of the TCP connections while doing redirection.
