Hi to everybody! I've got a little X-File here. I'm setting up a machine with a SuSE 7.1 to perform routing and firewall tasks. The problem is that I'm having problems connecting with one of my routers. I can access to every machine of my network except the router, and every machine of the network can access the router, except the Linux server. I'm using an Intel EthernetExpress PRO100 network cardin the Linux server; the router is a 3COM 826 for ADSL access. I'm really confused with this, I've never seen some like this before. Any ideas? Thanks in advance. José Carlos Cuéllar - jcarlos@alc.es Mecemsa Consultores - I+D Avda. de Dénia, 88 - E03016 Alicante Telf. +34 965 26 96 96 Fax +34 965 26 54 53 http://www.mecemsa.es

I think what you really need to do is: inside network | | eth0 linux router eth1 | | 3com 826 ADSL | | internet access The linux router will need two ethernet cards and two seperate cables as diagramed above. The default route of the linux router will point to eth1 address. All of the inside machines need to be pointed to the linux router eth0 address (default route). Networking is much easier to visualize when you create a small diagram with what you want to accomplish. Ken

Hi Ken. Yes, I know this will be the final configuration, but now I'm just testing the connection between the Linux server and the ADSL router. My current network is something like this: ################################### # # # Win Linux ADSL clients server router (sorry) All the elements are in the same network (192.168.0.0). The point is if somebody has ever had access from Windows machines to a router but the access has been refused from a Linux server. It should be some kind of misconfiguration in the Linux Server since I've set up a twin Linux server in another office with a similar configuration an everything works fine (SuSE 7.1 also installed). I've reinstalled SuSE 7.1 trying to resolve my problem, but it still doesn't work. I've got the option to format the hard disk of the server and install everything again from raw, but I'll prefer to try other options before :-) By the way, the router is from Cisco, not from 3COM; my apologies ;-) Again, thanks in advance for your help. -----Mensaje original----- De: Ken Schneider [mailto:kschneider@rtsx.com] Enviado el: lunes, 31 de marzo de 2003 19:14 Para: suse-linux-e@suse.com Asunto: Re: [SLE] Problem with ping to router On Mon, 2003-03-31 at 12:08, José Carlos Cuéllar wrote: problems

As long as the linux box (at this point it is NOT a router) has a correct IP address and the default route points to the cisco router there should not be a problem. I would use YAST and recheck the network settings before reloading the OS. It may also be an IP address conflict so check that as well. Ken

Does your Linux box have 2 network cards. If you want to use your linux box for routing tasks it has to stradle the barrier between the internet and you home network. Unless your home network has 2 subnets then you need the linux box to replace the hardware router. The linux box should connect directly with the ADSL modem and not with the ADSL router(unless your router IS your modem....then you have a few more problems). The other network card should connect to a switch or hub on your home network. Use the command 'ifconfig' to make sure your linux router has its network address properly configured. Other than that.... can you draw a simple diagram of your network configuration to help clarify. Also Can you be more specific on which machines can't talk with each other. If your linux box is not BETWEEN the internet and your home network, then there is absolutely no point in it performing routing/firewall tasks.
Thanks in advance.
