Router ADSL connected but i can't use browser or apt
Hello I have a problem with my router.
I just got the router from my telephone company and the router is already configured to work out and looks like is working. The router has a dhcp server and a firewall NAT. With windows xp everything works right, the dhcp server works and I can easely access internet, but I have a problem with Linux, I changed my network settings so Linux can accept the DHCP server and in fact doing a ifconfig I see that the DHCP server worked well. my computer has the correct gateway, the DNS has been configured. I try with a ping on google site and the ping is working but when I try to run the apt-get update or I try to use my web browser looks like I have no connection. I have installed a Debian Sarge and I tried on a Ubuntu as well but they give me the same problem. Can someone help me out? Sorry if my english is not so good :-( |
check your browser settings to ensure that there is not a proxy server set causing your problem. Also tell people what distribution you are using. This makes it easier to get a good response.

Just so you configure things correctly. If you are using dhcp then you need to set your network to pick up a lease from the router. If the NIC attached to the router is eth0 then the settings for /etc/network/interfaces would be;
auto eth0 iface eth0 inet dhcp Note that no gateway is specified because it will detect it. You need to specify the DNS addresses of your isp in /etc/resolv.conf; nameserver <ip-address supplied by isp> nameserver <ip-address supplied by isp> then do as root from a console /etc/init.d/networking restart Check that your system is picking up the lease by doing; ifconfig this should give details of the network interfaces and addresses. check that the system has a gateway by doing; route -n You should then be able to get out. |
then..
Ok I tried a few things and this are the results:
eth0 Link encap:Ethernet HWaddr 00:50:BA:6E:DD:40 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::250:baff:fe6e:dd40/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2335 errors:0 dropped:0 overruns:0 frame:0 TX packets:2266 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:606356 (592.1 KiB) TX bytes:169854 (165.8 KiB) Interrupt:11 Base address:0xe800 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:130 errors:0 dropped:0 overruns:0 frame:0 TX packets:130 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:8552 (8.3 KiB) TX bytes:8552 (8.3 KiB) ------------------------------------------------------------------------------ Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 ------------------------------------------------------------------------------ search nameserver 192.168.1.1 ------------------------------------------------------------------------------ Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination ------------------------------------------------------------------------------ I tried to use another DNS instead of the router ip but it works at the same way. I tried with a traceroute and it works no problem with a host name. Dont' know really what to do. Ohh I'm using a debian sarge. |
I would say your problem is with the DNS entry. This is a private range number and unless that address is running BIND and has a resolved public DNS address using NAT it's not going to function. The DNS address is normally a public address in order to resolve internet addresses. Your isp should have provided you with two DNS addresses for this purpose.
