Because I have 2 rigs with the same external IP and I connect to it, and the portforward via router to the PC.
For the easy portforward setup it could be better to modify ssh port from 22 to for example 23 for second PC.
Thanks.
Yes you can.
as root edit /etc/ssh/sshd_config
find line says:
Port xxxx or Port 22 or #Port 22
change it to:
Port the_port_number_you_want
for example:
Port 20022
then restart service:
systemctl restart sshd.service
Don't use port 23 as is reserved to telnet and better use ports above 1024
Keep in main you have to redirect ports in your router to those two pcs from public to private ports.
If you do it wrong you will have to get to the location of your pcs and fix it from terminal, so becarfull
Hope helps
