Cannot ping my router from from outside internet?
 

I am running my own web and mail server in ubuntu 13.10, my pc is connected to the D-link ADSL router that is working as dhcp server and default gateway for the pc, i want to connect to my web and mail server from the outside internet but it is not possible, when i ping my router external ip from the outside internet that is not working:
but i can ping from the lane.

this can be set on the gui of the rooter (if router accepts ping requests and allows access to your servers). They can be set more or less independently. Also you need configure local network and external connection too...

I assume pan64 is correct that your wan side icmp has been disabled or even not installed.

In some cases it might be blocked along the way for some reason.

icmp and ping are enabled in my pc firewall, i open the routet settings and didn't find any option to enable icmp and ping, the router firewall has a gui window (Add IP Filter -- Incoming) to allow incoming traffic, it is asking for the source ip and port number or range, for the source ip address didn't accept 0.0.0.0 i don't how to configure to accept icmp from the outside internet?

what kind of router you have?

My router is D-Link.

that is not really enough. D-Link has a page like this: http://support.dlink.com/emulators/w...ols_system.htm for all the routers. We may try to use that pages to check your setup, but you need to specify your router exactly.

Pinging the router generally has nothing to do with firewall. In most soho routers there is some option to enable external services. Pinging the external ip address should require the router to respond if it was enabled to do so. Most are set to disabled by default.

If you were to NAT the internal computer with some pin hole or go wild on a dmz(not recommended) it could allow you to then pass through to the internal client.

More than a few isp's block port 80. You then have to either map it on dhcp to some other port or let outside people know you are using a different open port.

Look on the 'Advanced LAN' tab. There is a check box to "Allow WAN ping respond".

Pinging the globally accessible IP address (175.109.93.153) will tell you if the router is up. The packet will not traverse the router to the internal web server.
