    If your ISP does not use PPPoE it is really quite simple. I included my laptop
    rc.conf just to show it plays no part:

      hostname="mneme.boltsys.com"
      moused_enable="YES"
      sshd_enable="YES"
      usbd_enable="YES"

      linux_enable="YES"
      nfs_client_enable="YES"
      nfs_server_enable="YES"
      nfs_reserved_port_only="YES"
      rpcbind_enable="YES"

    I take this system around to a site using cable, dsl, my office where I connect
    via a wireless network and, under duress dial-up. For that reason I boot up and
    then connect. Every where except for the office that is as simple as:

      dhclient ep0

    as that the antique NIC I use. Both the cable modem and the DSL modem I connect
    to provide DHCP on the inside. On the outside, the cable modem seems to get a
    fixed IP from its network. My DSL connection uses 192.168.0 addresses but all
    you have to do is connect to the modem as a gateway. My wireless setup:

      ifconfig wi0 wep wepkey 0x...
      dhclient wi0

    If your modem has a fixed IP adding

       defaultrouter="xxx.xxx.xxx.xxx"
       ifconfig_nic0="inet xxx.xxx.xxx.xxx netmask 255.255.255.0"
             or
       ifconfig_nic0="DHCP"

    to rc.conf should be all you need.

    You can of course do this manually by:

       ifconfig nic0 add inet xxx.xxx.xxx.xxx netmask 255.255.255.0
       route add default xxx.xxx.xxx.xxx

    I would then first try to ping an IP address and then a host name. If your ISPs
    DNS really is bad, you can change the hostname to localhost to avoid all the
    dns timeouts. If it all works, netstat -nr will have a line something like:

    Internet:
    Destination Gateway Flags Refs Use Netif Expire
    default 192.168.23.3 UGS 0 12052 wi0

    I hope this helps
