[ale] I've hit a rough wall, installin' Smoothwall :-)

[Courtney Thomas]

Jim,

Thanks so much for the explicit advice which I'll try tomorrow.

Happy Holidays,

Courtney

  Hi Courtney,

  It sounds like the DSL port on the SW box is not getting an IP address from the modem. The BOOTPROTO=dhcp line must be present in the config file for the NIC.

  Here is an  example:

  cat /etc/sysconfig/network-scripts/ifcfg-eth0
  DEVICE=eth0
  BOOTPROTO=none
  ONBOOT=yes
  IPADDR=192.168.0.2
  NETMASK=255.255.255.0
  GATEWAY=192.168.0.1

  So my nic IP is 192.168.0.2 and it's gateway is 192.68.0.1. But your nic on the DSL line needs DHCP so remove the IPADDR, NETMASK, and GATEWAY lines and change BOOTPROTO=none to BOOTPROTO=dhcp

  NOTE: I don't use SmoothWall so I'm not sure where the ifgcfg-eth0 file really is or it that is it's name.

  Try and restart networking and see if you get a real IP address. If not, hook up a single nic machine to the modem and try again. The modem may be in stupid mode - power cycle it and wait for the lights to settle before restarting networking.

  Pick an IP address for the other two NICs. It doesn't matter what itis as long as they are one seperate networks. So lets try green nic = 192.168.2.1 and orange = 192.168.5.1 .

  Now setup dhcp and use two networks from above. Those two ip addresses become the gateway for each network. You will also need to echo "1">> /proc/sys/net/ip_forward or nothing will flow between the branches.

    Jim,

    Thanks for the suggestion, which I attempted to implement this PM, without success.

    SmoothWall has recognized and loaded modules for all 3 NICs, so I assume they are ready to go:

    Ethernet cables plugged into the NICs:

        BellSouth DSL modem         [RED]        is 192.168.1.x;    i.e. whatever Bellsouth dhcp assigns...

        Lan ethernet hub             [GREEN]        is 192.168.2.2;    no LAN members plugged in yet

        Linksys wireless router  [ORANGE]        is 192.168.3.3;    with ethernet cable plugged into the "internet' port rather than any of the ethernet ports (4)

    DHCP Server is not enabled.

    It is unclear to me what the NIC addresses should be and as a result, I guess, I am unable, from the SmoothWall box, to ping any internet site by numeric or resolvable address.

    What's wrong and how should I fix it  ?

    Thanks,

    Courtney

        This makes no sense. I think the wrapping screwed up your diagram.  Just
        the same, I'd put the smoothie between the modem and the wireless router.



      Yes. The wrap moved NIC [Green] from the Smoothwall ethernet line.

      I recall smoothwall has a 3 NIC variant. I suggest adding a third NIC and put the wireless on that one. 

      modem -- [red] SW [green] -- internal LAN
                               [orange]
                                    |
                            wireless router WAN port

      Use SW capabilities for a DMZ to isolate the wireless off the LAN. Use a seperate IP space for dhcp on the wireless.
