Hello.
I have several rb433’s on different towers and have noticed that theres a lot of traffic to and from ports 137-139. Also, if a client does a network search it shows the other client’s pc. If these clients do not have a firewall active or simply is sharing a folder other clients on the network can access it.
I would like to prevent that from happening. Another thing I noticed is that viruses are propagating within our lan as well.
I have disabled the default forward option for wireless but haven’t noticed any differences.
How can I block or prevent these issues and not affecting the “normal” traffic?
Thanks in advanced for your help.
