Aliases? He's talking about three different machines I assume. And to your remark about 32-bit netmasks, that is not always true... > Here's an example for /etc/rc.conf: > > ifconfig_fxp0="inet 10.10.10.1 netmask 255.255.255.0" > ifconfig_fxp0_alias0="inet 10.10.11.1 netmask 255.255.255.255" > ifconfig_fxp0_alias1="inet 10.10.12.1 netmask 255.255.255.255" Like in this case. Here each should have a 255.255.255.0 netmask. One uses a 255.255.255.255 netmask on aliases when the alias address lies on the same network as the "real" address. > Unless you're going to setup packet filtering or the kernel based firewall, > then there is no need to activate the options you were told you needed.... He want's do do NAT. He needs IPFIREWALL and IPDIVERT. > The basic kernel supports mutiple IP address aliases by default. His subject line is skewed from the real topic. I'll change it in this reply. Anyway, on to the compile problem. Please humor me. Go to the build diretory and try, # make clean depend all Again. If you get that error, please send your kernel config file to the list. As well as the error message including the few lines leading up to it. Where did you get your source tree? -- Crist J.
