Hi,
What I want to accomplish is this: I want to connect with my laptop to my
server ssh port 22. This rule is easy and is working very good. Butt when my
laptop have an established connection with ssh, I want port 234 to open on
my server.
So when i'm NOT connected on my ssh, TCP port 234 is closed. when I login to
my ssh port I want TCP port 234 to open (only to me if possible.)
I looked for this butt the only thing I can find is with port knocking. Then
I was thinking to use dyndns so i can use a normal rule to accept 234 to my
laptop dynamic ip, but how do I usemylaptop.dyndns.org in my rules?
Sincerely,
Selvam Matthys
