Hello people!, I'm trying to configure 2 network interfaces in the same subnet, because i want to use one interface for NS and the other for MX, if i try bash-2.05b# ifconfig em0 aa.bb.dd.1 netmask 255.255.255.0 bash-2.05b# ifconfig em1 aa.cc.ee.2 netmask 255.255.255.0 ifconfig: ioctl (SIOCAIFADDR): File exists ok they both cannot be in the same subnet. i know that i cannot have them both in the same subnet without modifying the routing, but im confussed about it. i also tried after settin' one of the ips, deleting the routing bash-2.05b# route delete aa.bb.cc.0 and then setting the ip bash-2.05b# ifconfig em0 aa.bb.dd.1 netmask 255.255.255. ok i can now set the 2 ips in the same subnet but my DNS stops working, i dont want to change the submask, for any of my ips well im confused about it, so i hope you guys could adress me in the right direction, Thanks in advance, Alfredo
