I have created a topolgy in packet tracer displaying two networks. I have cpnfigured VLANs on both of the networks and configured access control lists. However, I would like to configure access control permissions based on read and write. I want both networks in the topology to be able to read one another information but deny access to make changes. In a nutshell, I would like network A to be able to read files or any other form of data stored on Network B and for Network B to deny change permissions so that Network A cannot alter any information on Network B. Could you please provide me with the right configuration to use. Thank you.
Access control lists operate at layers 3 and 4 of the OSI or TCP/IP model. File operations like reading and writing are application layer functions, so network ACLs have little or no control at that layer.
If you think about it, reading a file can be very different depending on the application. Are you using FTP? A word processing program? A database application? Each one has its own unique ways of reading a file. At the network layer, these are all invisible to you.
