My guess about tmdns is based on the fact that you are using routable addresses. That is not normal. It is definitely not normal for an ADSL router. It also may cause additional problems. I am not a networking guru by any means, but if you run a DHCP server that assigns routable addresses, you must also couple this with routing tables and DNS entries that get updated for the target machine. If you have a single connection (ADSL) to the ISP, I don't think that it is possible to have multiple routable IP addresses that all go through that single LAN connection without some kind of central router device to perform NAT. Normally, an ADSL router is not authoritative for a DNS server, so assignments from your ADSL router do NOT get updated into the DNS tables/routers of your ISP's network. This understanding is based on the idea that you have a single MAC address for your router and a single LAN connection (ADSL). Thus all network traffic to your ISP and Internet appears to be coming from a single network device. Normally, the ADSL router assigns internal addresses to separate devices and routes the packets back to the individual originating devices. In your case, the address is routable, which means that ISP DNS is responsible for sending the packets back to the device which is different than the ADSL router that made the original request. So, your ADSL router sends a packet request and the return packets get routed back to whereever authoritative DNS says that IP sits rather than back to the ADSL router. Normal path like this: Machine1 \ <--> ADSL Router <--> ISP <--> Internet / Machine2 And follows the same return path back again. With your setup, the path seems more like this: Machine1 <--<-- \ \ --> ADSL Router --> ISP --> Internet where the return packet bypasses the ADSL Router and gets routed directly to Machine1 by the DNS of the ISP which is authoritative for routeable addresses on their network. So, either I am missing something obvious about your setup or you have left me confused about what your network architecture really is. > How do I disable tmdns? service tmdns stop chkconfig 2345 tmdns off But see my note above. I should suggest that you take a look at the current configuration settings for your working router device and try to replicate those settings over to the new device. That might be the shortest route to get a working connection. Your ISP may have an expected MAC address for the router that you need to clone to use the new router. -- Bryan Phinney Software Test Engineer Want to buy your Pack or Services from MandrakeSoft?

[newbie] Suddenly can't access internet.. DHCP problem?
Hi, I bought a new adsl router today, and so unplugged the old one, plugged in the new one, set it all up via the web interface using a computer with WinXP on it. Set the router to use DHCP, and a WinXP laptop and desktop both are happily using the internet. Now.. to my Mandrake 9.2 machine. Used drakconnect and tried to put in my settings.. and I just can not seem to get it on the internet. I have tried setting it to use dhcp, or with a static IP, to no avail. Worse, I can now access my mandrake box via my windows pc.. so it does have an IP address.. but the mandrake box cannot access the internet, and the internet can not access the mandrake box. Am I insane, or am I missing somehting obvious? My settings: gateway: xxx.yyy.50.104 subnet: 255.255.255.248 The windows machines pick up the DNS automatically.. and I have tried this with mandrake, and by also manually setting the DNS. Can anyone offer advise.. or slap me round the head for being stupid? -- Azrael - Everyone should have http://www.freedom2surf.net/ Want to buy your Pack or Services from MandrakeSoft?
