Well, I seem to be getting somewhere, although where exactly is open to question. I did this. I put the virtual interface address 192.168.0.1 back onto eth1 of the gateway host and restarted the network services. The ifcfg file looked like this: BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0 ONBOOT=yes ONPARENT=yes After the restart ip addr showed this: 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:25:90:60:11:8d brd ff:ff:ff:ff:ff:ff inet aaa.bbb.ccc.1/24 brd aaa.bbb.ccc.255 scope global eth1 inet 192.168.0.1/24 brd 192.168.255.255 scope global eth1:192 inet6 fe80::225:90ff:fe60:118d/64 scope link valid_lft forever preferred_lft forever Note the cidr suffix on 192.168.0.1 = 24 That is not what I expected. Restarting with the same config did not change the initially observed outcome. SO, I edited ifcfg-eth1:192 and added exactly one line: PREFIX="16" and restarted the network. ip addr now shows this: 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:25:90:60:11:8d brd ff:ff:ff:ff:ff:ff inet aaa.bbb.ccc.1/24 brd aaa.bbb.ccc.255 scope global eth1 inet 192.168.0.1/16 brd 192.168.255.255 scope global eth1:192 inet6 fe80::225:90ff:fe60:118d/64 scope link valid_lft forever preferred_lft forever Note that the cidr suffix is now 16. Now, when I try and ping an address on the 192.168 netblock from host C I see this: # ping 192.168.209.43 PING 192.168.209.43 (192.168.209.43) 56(84) bytes of data. >From 216.185.71.1: icmp_seq=2 Redirect Host(New nexthop: 192.168.209.43) >From 216.185.71.1: icmp_seq=3 Redirect Host(New nexthop: 192.168.209.43) >From 216.185.71.1: icmp_seq=4 Redirect Host(New nexthop: 192.168.209.43) >From 216.185.71.1: icmp_seq=5 Redirect Host(New nexthop: 192.168.209.43) >From 216.185.71.1: icmp_seq=6 Redirect Host(New nexthop: 192.168.209.43) My question now is how do I get to 192.168.209.43? -- *** E-Mail is NOT a SECURE channel *** James B.
