Well, it is a design flaw to have 3 addresses in overaping networks. From what I recall you may use only one non /32 address in a network. If the requirement is not met, problems arise: Problem: You want to broadcast to 192.168.1.255. Question: From which of these addresses should it origin? Problem: Someone else broadcasts to 192.168.1.255. Question: Which of these addresses should catch it? One? All? I was taught that configurations of multiple-ip-per-net should look like: config_eth0=( "192.168.1.2 netmask 255.255.255.0" "192.168.1.3 netmask 255.255.255.255" "192.168.1.6 netmask 255.255.255.255" ) Only the first has a regular mask (and therefore is source and target for broadcasts) - the rest has /32 mask and is only valid for unicast communication. AFAIK this is true for both multiple cards on single network and multiple aliases on single card. -- Pawel Kraszewski www.kraszewscy.net -- gentoo-user@gentoo.org mailing list
