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?
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.
