today i have to get the system running, but i'm not sure if the
configuration i want to make, will run. Maybe the people in this
list will make some suggestions on my ideas.
First of all i want to say "Thank you very much" to:
 - Daniel O'Callaghan
 - Joe Greco
 - Narvi
 - Richard Wackerbarth
for their replies.
Now what i want to do today as follows. Please make some suggestions,
corrections or commitments on this. Again the picture is appended
1. The router is a KA9Q-ISPA-router, not capable of bridging.
2. The machines on the private company network (192.168.3.x) need
   a gateway (the FreeBSD-box) and this gateway should be the
   WWW-server, WWW-proxy and SMTP-server. I was told, the gateway
   (the FreeBSD-box) has to have a IP in the private company network
   (192.168.3.x), because they are all Windows machines and Windows
   needs this (i don't know if Windows does it really need).
3. ifconfigs for the FreeBSD-box:
      ifconfig ed0 inet netmask 0xffffff00
      ifconfig ed0 inet netmask 0xfffffc00 alias
4. I'll config the NE2000-device of the router to with netmask 0xffffff00
5. I'll change the 100MBit-device of the router to with netmask 0xfffffc00
Please make some suggestions on this configuration.
- Will this configuration work ?
- Will the packets of the FreeBSD-box addressed to the internet, be
  routed through the ISDN-line ?
- Will the packets from the private company network find their way to
  the gateway (the FreeBSD-box) ?

Remember, i have not the option of changing the physical configuration
of this network, since it is a 100 MBit network based on HP-10/100-VG
and Compex-100VG4 network-cards and FreeBSD-2.1.x does not support them.

Many thanks in advance for all suggestions and helpful hints.
When i'll get this bogus network running, i'm sure, the boss will be
impressed and another friend of FreeBSD is born and maybe the ISP
starts thinking about Operating-systems as well defined and behaved
systems and stops thinking about OS's as hacking-systems.

As promised, here is the pictured configuration:

                  | FreeBSD-2.1.0 |
                  ||   NE 2000   ||
                  || ||
                  || ||
                 || NE 2000       ||
                 ||    ||
                 |                 |
                 |         +-------+
                 | Router  | ISDN  o------------o ISP  1.2.3.x
                 |         +-------+
                 |                 |
                 || 100 MBit      ||
                 || ||
                 ||   100 MBit  ||
                 || ||
                 |               |
                 |  192.168.3.x  |
