I recently erased all of the Virtual Server rules from a D-Link router and added just the ones that I needed (for example I don’t need DNS or NetMeeting, etc.) You can see the defaults on the emulator.
A strange thing I’ve noticed is that the default rules set the private IP for all of the services set 0.0.0.0 but when I try to do the same, it gives the following complaint
Invalid Private IP of LAN Server.
I can set them to a local IP (ie 192.168.x.x) though.
I am curious as to what the deal is. Is that a bug in the router? In fact, I have been wondering about 0.0.0.0 IP address for several years, especially in regards to servers (web servers, etc. often talk about binding to 0.0.0.0).
