IDP Support Notes

What does "Stealth" mean, why should I need it?
When you enable Stealth mode on an interface (WAN/LAN/MGMT), it will not
respond to any type of traffic intended for it; it will not respond to traffic like ICMP
echo request.
Before hacker/cracker could infiltrate your network, hacker/cracker would need to
take down your ZyWALL IDP before attacking your internal network. Configure your
ZyWALL IDP’s interfaces in Stealth mode, so hacker/cracker would not be able to
attack it.
I can not remote manage my ZyWALL IDP 10 at home, why?
By default, ZyWALL IDP 10’s WAN port is in Stealth mode to prevent hacker from
entering ZyWALL IDP 10. It’s recommended always use MGMT port to configure
ZyWALL IDP 10.
Why should I define Policy Check on WAN/LAN port?
Attacks could come from internal network (LAN) or from external network (Internet),
therefore not only do you need to define policy check on WAN interface, but also on
LAN interface.
