What security risks do I open up to *all* machines on my LAN by *disabling*
the "Block WAN Requests" option on a 4 port LINKSYS Router? The scenario is
I have two computers behind a LINKSYS Router Firewall (4 port hub) and use a
cable modem service as my ISP. I do *not* want my private laptop pinged
because it's private. The other machine is a desktop IIS server which I'm
using for testing purposes and I need to be pingable (I think) because I
want to be able to hit the web server from outside my LAN. I set it up to
bypass the router by including this LAN IP address as the DMZ. In order to
ping this same machine outside the LAN, I had to disable the "Block WAN
Requests" option. However, I'm not sure if this opens up the other LAN
address assigned to the laptop (not part of the DMZ) to the WAN as well. My
primary concern is what this does to the security of my router. Does that
mean my router is now "pingable"? If so, why would this be a concern?
Insight is appreciated...
