Here's what i've tried so far:
I have setup my NAT using the 10.0.0.0 range.
I set up the one of the NATed PCs to be a NAT server as well (using the
192.168.0.0 range). I've put a second network card in it and on this second card
I have connected another PC (the new 192.168.0.0 sub-NAT-network).
More or less the following situation (where you see a '#', it is a network
card):
10.0.0.0 PC3 192.168.0.0
+----+ +-PC1 +----+
|1st | | |2nd |
world<---#NAT #----+--------#NAT #-----PC4
|serv| | |serv|
+----+ +-PC2 +----+
The problem is that the when I give on PC3 "ifconfig fxp1"
(my second network card that gives to PC4) I get the frustrating message "no
carrier".
And of course PC4 gets "no rout to host"..
Any ideas??
thanks,
dimitri & paisios,
PC. I use no DHCP ..
