Failed WAN connection

Buckyjunior · 10-10-2004, 12:05 AM

I've been looking for days to find a problem similar to mine, but cannot. If I am repeating a thread, I apologize. My problem is that I cannot access the internet with my Linux box, nor is it accessible from the outside.

My Linux box, running Fedora Core 1, as my other computers running other OS's, is connected to a D-Link DI-604 router. I've set my linux box to have the static IP address 192.168.0.138, enabled virtual server HTTP and set that IP address as "DMZ."

I can make connections from the other computers on my LAN through ssh and with a browser, pull up http pages. If I try to connect through my WAN IP, I get nothing. From the Linux box, I can ping the other machines on my network, but cannot ping anything outside.

I've checked and double-checked the settings on the router, rebooted the router, rebooted the cable modem. No help.

ifconfig looks like this:

Code:

eth0      Link encap:Ethernet  HWaddr 00:03:6D:12:44:22  
          inet addr:192.168.0.138  Bcast:192.168.0.255  Mask:255.255.255.0

          collisions:0 
          RX bytes:2181528 (2.0 Mb)  TX bytes:2181528 (2.0 Mb)

I've looked at /etc/hosts, /etc/host.allow, /etc/host.deny, iptables, and nothing seems to lend itself to finding the answer of why I have a block here. I'm frustrated, tired, and giving up for the evening.

I would be thankful for some assistance.

did you set the default gateway to the dlink router and have DNS servers in /etc/resolv.conf?

Ah, the default gateway. It *had* been set to the D-Link router then it stopped being able to go in and out. I had changed it to the IP's listed gateway where it worked for a day or so.

Now that I've changed it back to point to the D-Link, I'm back on line. I can access the internet from the linux box and I can access the linux box using my dhcp assigned IP address.

Thanks for your help.

Now, I need to move on to other issues that have been nagging me for months now. They're different topics so I'll run them in different threads.

Appreciative,
Bucky
