I have a ZTE Modem router using it to get internet connection for a home PC, I opened the tab : security and under it choosed "firewall".
I found that the option : "enable anti hacking" is unchecked. According to ZTE help, checking this option protects against (ping flood, ping to death, sync flood attacks).
And I found the option " Firewall level" is set to high, and a small hint below it is written as follows : "Allow legal WAN side access, but prohibit Ping from WAN side."
I checked the " enable anti hacking " option.
But I'm asking, I there a possibility that I have been hacked in the period before I enable this option or this is impossible because the firewall is set to high which prevents WAN ping?
The router model is " ZXHN H108N V2.5"
Thanks in advance.
