Hi,How i can open port forward on my linux server
 

Hi,How i can open port on my linux server and forward it to my port on my computer when i have communicate with the server using vpn connection [pptp]
example :
1-remote server dedicated ip is x.x.x.x
2-my vpn ip is 10.10.10.230

i need to forward port 443 on x.x.x.x to port 443 on 10.10.10.230

i have tested this command but not worked :
ssh -4 -L 443:10.10.10.230:443 root@x.x.x.x

Maybe ssh root login is disabled on the server. This would seem like a good idea for a server.
