Thanks for the advice, Richard:
Richard> I think you have to turn on proxy-arp : Richard> echo "1" >/proc/sys/net/ipv4/conf/default/proxy_arp Richard> .../eth0/...
I gave that a try. I got the same problem:
[root@host225 /root]# echo "1" >/proc/sys/net/ipv4/conf/default/proxy_arp [root@host225 /root]# /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 00:10:F3:01:11:1F inet addr:207.168.228.80 Bcast:207.168.228.127 Mask:255.255.255.192 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:42687 errors:0 dropped:0 overruns:0 frame:0 TX packets:18766 errors:0 dropped:0 overruns:0 carrier:4 collisions:6379 txqueuelen:100 Interrupt:11 Base address:0xe000
