I have a Netgear wireless router that has an ip address of 10.3.30.110 on the network (as per the router config. page). Using my Fedora box that is connected to the router, I can access the internet fine, it has a private address of 192.168.1.2. I can also ping the router's private address i.e. 192.168.1.1.
However, for some reason I cannot ping 10.3.30.110 either from the Fedora box OR from a computer that is not in my private network! I tried releasing and renewing the router ip, but same thing with the new ip.
The reason why this bothers me is because I wanted to se VNC, and this may be part of the problem why the VNC wouldn't connect.
I'm assuming the router is setup to respond to ICMP type 8 echo requests? Many turned off this feature or started shipping it off by default after blaster (I think or slammer) in 2002. Anyway, to use vnc with a router you need to open a port on the firewall to accept connections through whichever vnc runs on. I'm also assuming your router is using NAT.
Thanks for the reply. I have no clue whether it is set up for ICMP type 8 echo requests, couldn't find in in the config page. It does use NAT though.
The thing is that to use the VNC from outside I would obvioulsy need to use the ip of the router i.e. 10.3.30.110. But since I cannot ping it, it seems inaccessible. I searched google but have not found anything similar to this.
I assume that IP is the internal IP of the router. What is your externally accessible IP - ie the one on the internet?
EDIT: The ability to turn off ping responses is usually under security or some similar heading. Just look for ICMP or ping. The router interface page should also give the external IP, usually at the first page you come to.

I turned the "internet ping" on, but no luck. Still can't ping from outside the private network i.e. 192.168.1.x
The ip 10.3.30.110 is the ip obtained by the router using DHCP on the server, this is a larger network, not the internet. I do not need to access it from outside the 10.x.x.x network.
