Hello Petra,

The "status:" line wasn't different? I think it should be...

Here is what I have on my system:

  From dmesg:

  ex0 at cardbus0 dev 0 function 0: 3Com 3c575B-TX Ethernet
  ex0: interrupting at 9
  ex0: MAC address 00:50:da:99:e6:ae
  tqphy0 at ex0 phy 0: 78Q2120 10/100 media interface, rev. 11
  tqphy0: 10baseT, 100baseTX, auto

  From /etc/ifconfig.ex0:

  inet 161.134.131.53 netmask 255.255.255.0

  From /etc/mygate:

  161.134.131.1

  From ifconfig ex0:

  ex0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: Ethernet autoselect (10baseT)
        status: active
        inet 161.134.131.53 netmask 0xffffff00 broadcast 161.134.131.255
        inet6 fe80::250:daff:fe99:e6ae%ex0 prefixlen 64 scopeid 0x13

And as Rene Hexel's email already pointed out, you are using the default
gateway IP address for the network card, which is probably not what you
want.

Assuming that your machine is connected to a network that can access other
networks, you want to use the default gateway for your network as the
contents of the /etc/mygate file (or set this up through the /etc/rc.conf
files.

In my case, my IP address is 161.134.131.53 and sits on an internal
161.134.131.0 network. The router that sits on this network is using the
IP address 161.134.131.1, and that is what goes in my /etc/mygate file.

With this configuration my routing table looks like this:

palomino:bstark$ netstat -rn -f inet
