I am having difficulty setting up a secondary ip address on my network card in Ubuntu 12.04 server running VirtualMin 3.98.gpl. When adding the secondary address, I can ping the primary and secondary address from a machine on the same network, but from any other network, I can only ping the primary address. Assuming I am using the command correctly, I can also ping "out" from the secondary address using ping -I eth0:0 . For the secondary address, everything acts like a nic with no gateway configured, but it is supposed to use the gateway of the primary address, right?
My goal is to allow access to an nfs export though this address (yes, there is a reason why I'm not using the default address)
This has to be something obvious I'm missing. I've even tried creating a Virtual Server and assigning it the virtual ip address to gain access with no luck.Any suggestions how to troubleshoot further?
