Cannot access Internet through SUSE 9.2 Pro router
I am unable to access the Internet from my internal network through a SUSE 9.2 Pro box that I'm trying to configure as a router.
Here's what I'm doing: Set up eth0 as a DHCP client. eth0 is the interface connected on the "Internet" side. My ISP is Comcast, which assigns a dynamic IP. Go into YaST -> Network Services -> DNS and Host Name -> Set host name, and tick "Change host name via DHCP box" -> "Finish" Set up eth1 with IP address of 192.168.0.1 with subnet mask of 255.255.255.0. Set up eth1 as DHCP server (obviously for serving internal IP addresses). Set up routing: YaST -> Network Services -> Routing -> I put in gateway, and tick "Enable IP Forwarding." -> "Finish" I then set up the firewall, with eth0 as the external interface and eth1 as the internal interface. I have allowed the SSH and DHCP ports to remain open. I ticked the "Enable Forward Traffic" and "Do Masquerading" boxes. I have copied /etc/resolv.conf from the router box to the client boxes. From here, I can ping google.com successfully from the router box. I can ping all the internal machines from the router box. I can NOT ping any known Google IP from any of the internal client machines, nor can I ping the actual "google.com" domain. In other words, none of the packets are making it through, not just the requests doing a DNS lookup. I have been trying for about a week, for a total of about 16 hours to get this working, including looking at a ton of tutorials, articles, and other examples. If you have other documentation you can point me to, or something else I can fix, set, or check, please let me know. I'm just about at my wit's end with this. I do appreciate any help. |
Can you ping the router box from the client boxes? Have you checked what the DHCP service is issuing to the clients to make sure it is accurate?
Sounds like a simple thing to me, you may just want to go over the settings one by one and try to look at it as if you were looking at a friend's machine that had a problem you wanted to figure out. Look at it new and you'll spot things. |
Yeah....
Thanks for the ideas. I actually started trying to do this about a week ago. I put it aside for a few days, to get a fresh look at it.
Yeah, I can ping all machines from the router and vice versa. They are all getting valid IP addresses. The only thing that is not happening is that I can't get those internal machines out past that internal interface. They can't ping any domains (google and yahoo being the main ones I tried) or their IP addresses. I just don't know what else to check. I have been over and over this on several different machines several times. I know it has to be some simple thing that I'm missing... I'm just not able to ascertain exactly what that is. It's quite frustrating. I do appreciate your help! Thanks again. Any other thoughts? |
Got it
I figured it out. I think I had something screwed up with the firewall. Anyway, for a great tutorial on setting this up, check this one out:
