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
Thanks in advance,
