Hallow all, I have a network numbering/routing question. I have a pretty standard home network with a linux firewall/NAT box feeding a hub to what is is usually 3-5 machines. Can I eliminate the hub and use 3+ nics on the firewall box and 'how' would I number them??? I have set this up once before but I find that the various hosts connected to the firewall can not see or access each other, but all can access the net. what am I doing wrong below ? Internet==> firewall/NAT Machine [with multiple Nics and CrossOver CAbles to Hosts] ==> ==> eth0 [ 10.0.0.1/255.0.0.0] ==> host-1 eth0= 10.0.0.2/ 255.0.0.0 ==> eth1 [ 172.16.0.1/255.255.0.0] ==> host-2 eth0= 172.16.0.2/255.255.0.0 ==> eth2 [ 192.168.0.1/255.255.255.0] ==> host-3 eth0= 192.168.0.2/255.255.255.0 The method above did now allow each host to see & access each other, they could access the internet. Could the following Alternative Numbering Work ?? Internet==> firewall/NAT Machine [with multiple Nics and 'CrossOver Cables' to 'multiple' Hosts] ==> ==> eth0 [ 172.16.0.1.255.255.0.0] ==> host-1 eth0= 172.16.0.2/255.255.0.0 ==> eth1 [ 172.17.0.1.255.255.0.0] ==> host-2 eth0= 172.17.0.2/255.255.0.0 ==> eth2 [ 172.18.0.1.255.255.0.0] ==> host-3 eth0= 172.18.0.2/255.255.0.0 Thanks in advance for any guidance you can give me.
