I have latest ZA Free on Win7SP1. I am unable to ping either 127.0.0.1 or my own computer which is 192.168.1.2 . However, if I turn ZA off, then I can ping them. If I ping 'local host' I get : : 1.
I have added name = localhost
entry type= ip address
to ZA firewall, and also have reset ZA by CTRL+SHIFT, Reset on menu. My LAN is in the firewall and I can ping all other devices on the network. It does not appear to cause any problem but I would like to be able to do it.
