I bought and installed Norton Security with Backup in June, 2015. It's firewall blocks access between computers on my LAN unless I turn it off.
I've searched the forum, but all of the similar posts are from around 2012, and the instructions given don't apply to my version of the product.
Any suggestions other than turning off the firewall (which works, but is a little scary since I have port forwarding access to the computer in question enabled through my router firewall)?
