You can find an example firewall that will block unwanted traffic to the CPU.
I would like to see and study that example.
Is it somewhere on the same page? Couldn’t find it.
Where is this example supposed to be? Is it on some other web page? A link would be fine.
Unclear on which device to perform: on R1 or R2, or on both?
The command to do that is missing. It instead just shows the “print”.
Adding new user named “serial” and binding it to the serial port:
Unclear on which device to perform: on R1 or R2, or on both?
Unclear if after closing the session a reboot on the devices R1 and R2 is necessary, but it seems indeed necessary.
Has this to be done locally on the devices, or can it also be done from remote, ie. from PC?
Do both devices, R1 and R2, need to be rebooted?
What about reverting point #1, ie. re-binding console to the serial port ?
And also what about that user “serial” created in #2 above? Does its link to the serial port need to be terminated?
And the Description says:
Special login can be used to access another device (like a switch, for example) that is connected through a serial cable by opening a telnet/ssh session that will get you directly on this device (without having to login to RouterOS first).
Without having to login to RouterOS? Really?
But he uses ssh to login to the device. Is he by that not doing a login to RouterOS?
But then people would rightfully complain that these addresses cannot be used in real networks…
OTOH, a simple footnote saying that these IPs are just placeholder-examples in documentations should do the trick.
I actually asked them to introduce errors in the documents you are reading so as to keep you away from asking configuration questions. So far its working.
