I just installed OpenVPN Access Server on a Debian server with an internal IP of 172.16.99.12
I configured the OpenVPN host address to be the public IP of the router that the server is connected to directly, using only TCP, and port 443. I (believe I) then configured my MikroTik router to direct any traffic directed at port 443 of it's public IP to be sent to the server's local address, also on port 443.
The rule I added to the firewall is as follows:
Chain: dstnat
Dst. Address: (router's public IP)
Protocol: TCP
Dst. Port: 443
Action: dst-nat
To-Addresses: 172.16.99.12
Dst. Port: 443
When I try to connect to the router's public IP using the OpenVPN client on my Windows 7 laptop, the connection times out.
I have very little experience with VPN and port forwarding, and help is much appreciated.
