[SOLVED] port forwarding in linux

hnasr2001 · 01-11-2018, 01:36 PM

Hi;

I have a computer belong to a private network behind a router. Router has been setup for port forwarding (input port is 6522 and target port is 22)

What would be the ssh command to connect from mypc@mypc to the one in the private network private@private?

Code:

ssh -p 6522 username@public_IP_address

The private computer should be configured with a static IP address or use the router's DHCP address reservation so it is always assigned the same IP address. Will let others explain security by obscurity and how just changing port numbers will not really make your system more secure.

Thank you.

If I want to use the "scp" command, will the command be :

scp -p 6522 username@public_IP_address ?

Take a look at the man page for scp syntax. It uses -P instead of -p to specify the port number. You also need to specify the source and destination directories and files to be copied.
