Hi,

After all your tips. the routing finally seems to work. I hav eonly one 
problem left, when this is solved I will post a message explaning how 
everything worked out. This might be helpfull for people with the same problem.

Here's my (last?) problem:

I still have the configuration:

MS-WINDOWS            FreeBSD                        FreeBSD
<no name>             router.jcn.nl                  host.jcn.nl
netmask 0xffffffc0    0xffffffc0                     0xffffffc0
193.78.175.138        193.78.175.129 193.78.175.66   193.78.175.65
     |                      |              |                |
     \----------------------/              \----------------/

I use two seperate ethernet because one of them has to be replaced with a 
leased line so the host.jcn.nl-machine can move to another building.

The routing seems to work, but when I want to use FTP from the 
MS-WINDOWS-machine:
ftp to router.jcn.nl goes fine
ftp to host.jcn.nl also goes fine
BUT: when I try to ftp to 193.78.175.129, and look at the traces in Winsock:
id=0008 fl=0100 
Questions
193.78.175.129 0001 0001
; size = 32
sendto(2,0C57:0000,32,0,085F:86CC,16)

recvfrom(2,0C57:0000,1024,0,085F:86CC,<16>)
recvfrom(2,0C57:0000,1024,0,085F:86CC,<16>)
recvfrom(2,0C57:0000,1024,0,085F:86CC,<16>)

the resvfrom-message repeats about 200-300 times. When I press the CANCEL 
button in the FTP client-program, the connection is made imediatly. It looks 
to me like the MS-WINDOWS machine is trying to look up the name of 
193.78.175.129???
But the nameserver (193.78.175.129) seems to be configured correctly, when I 
try 'nslookup 193.78.175.129' on the FreeBSD machine (host.jcn.nl), I get:

host# nslookup 193.78.175.129
Server:  router.jcn.nl
Address:  193.78.175.129

Name:    router.jcn.nl
Address:  193.78.175.129

BTW when the recvfrom messages come along, I don't see any increases in the 
Ipkts and Opkts on the FreeBSD machine, so nothing seems to be transported 
over the Ethternet?

Does anyone know what the recvfrom-messages mean and why they apear so 
often. The recvfrom messages take about 30 sec.
