Hello folks,
I have a web server running on port 80 and a SSH daemon running on
port 22. I don't want to change these ports because it just works this
way.
Can I configure iptables that it just accepts port 80 and if I try to
connect with a ssh client to port 80 to forward this ssh traffic to
port 22? I know how all this accept and forwards stuff works, but I
can't find out an option to recognize ssh traffic.
You might want to take a look at port knocking:
