Yes, but I use it as a relay agent.


It was a pppoe link.


O.K.
Let's leave this configuration alone and try to resolve the second box
with a fresh install and with no firewall and no adsl.
This is the scenario:

Second freebsd box with two nic:
First nic IP 192.168.0.100 is connected to a switch and to the switch are connected
two windows pc (one 192.168.0.201 and 192.168.0.202).
Second nic IP 10.0.0.100 is connected to a hub and to the hub is connected a
windows pc with an IP of 10.0.0.200

The FreeBSD box can ping the two windows pc 192.168.0.201 and 192.168.0.202
The FreeBSD box can ping the windows pc 10.0.0.200
The windows pc 10.0.0.200 can't ping the two windows pc 192.168.0.201 and
192.168.0.202
And ofcourse the two windows pc 192.168.0.201 and 192.168.0.202 can't ping
the windows pc 10.0.0.200

On the FreeBSD box I have sysctl net.inet.ip.forwarding=1

I see. This was the problem that I could not understand. So you have in fact two parallel connections to the ADSL modem, one for administration and one for internet.

Stay with the setup we had before you made this post. Set the ADSL modem's IP to 192.168.100.1.

We removed the IP for fxp0 earlier, but now we need it again. Set it to 192.168.100.2.

Now?

M.

Can I set the IP of fxp0 to 10.0.0.50 and for the adsl to 10.0.0.2
the reason that I'm asking is because the adsl modem already have 10.0.0.2
and it's almost impossible to configure the adsl modem via lynx, this is the reason
that I want to access the adsl modem via a windows pc.

You can use the 10.* addresses for the modem, but then you must reconfig the windows machines to use a different one instead.

They cannot be in the same subnet, this is the only thing to look out for. Make logical subnets match physical.

O.K.
Now the fxp0 IP address is 10.0.0.50 and the nic is connected to the
adsl modem.
The adsl modem IP address is 10.0.0.2
The second freebsd IP addresss ramain 192.168.0.50 and it's connected via a switch to the
windows pc (192.168.0.200).

Windows pc 192.168.0.200 can ping 192.168.0.50
Windows pc 192.168.0.200 can ping 10.0.0.50
FreeBSD box 192.168.0.50 can ping windows pc 192.168.0.200
FreeBSD box 192.168.0.50 can ping adsl modem 10.0.0.2
Windows pc 192.168.0.200 CAN'T ping 10.0.0.2

Ok, good. Now you have to set a route on the ADSL router so it knows that it can reach 192.168.0.* via the internal interface (gateway 10.0.0.50) and not on the internet.

So you say that the problem is not on the freebsd box and I have to set a route
on the adsl modem itself?

yes.

O.K.
Thanks very much for your time and for helping me.
