When you assign IP addresses to interfaces, you give them a subnet they know they can find on the Ethernet segment connected to that interface. Where should your computer send traffic for 192.168.1.100? Out which interface? > zeus# ifconfig rl0 inet 192.168.1.145 netmask 255.255.255.0 > ifconfig: ioctl (SIOCAIFADDR): File exists This error occurs when FreeBSD tries to overwrite the routing info set by the ifconfig statement for the first NIC. Do a `netstat -rn` to see relationships between subnets and interfaces. > Any ideas for getting this NIC up and running properly?? Use a different IP network for it: ifconfig_dc0="inet 192.168.1.144 netmask 255.255.255.0" ifconfig_rl0="inet 192.168.2.1 netmask 255.255.255.0" Or use a smaller IP network for it: ifconfig_dc0="inet 192.168.1.144 netmask 255.255.255.0" ifconfig_rl0="inet 192.168.1.253 netmask 255.255.255.252" But if 192.168.1.0/24 is in your routing table, its traffic goes out of one, and only one, interface. -- Paul Chvostek <paul@it.ca> it.canada http://www.it.ca/ Free PHP web hosting! http://www.it.ca/web/
