Traffic block just in one direction
I currently have a switch ACL blocking traffic from the normal network (51) to my IoT network (54).
Now I want to explicitly access a system on the 51 via SSH from one of the IoT machines in the 54 network (i.e. the opposite of the rule).Unfortunately this access is blocked. Even if I create another rule and set it to position 1, the access does not work.
Only if I switch off the rule "Normal to IoT block" it works. How can I achieve that the basic access from the normal network to the IoT network remains blocked, but this one communication path is open?
