Thats because ip aliases have to have the netmask of 255.255.255.255, it used to not be enforced, now it is.

Subject: 4.6-PRERELASE fxp alias woes
Greetings all,
I cvsup'd to the latest -stable last night (4.6-pr):
FreeBSD homer.wmis.net 4.6-PRERELEASE FreeBSD 4.6-PRERELEASE #3: Mon May 13 12:22:11 EDT 2002 root@homer.wmis.net:/usr/obj/usr/src/sys/HOMER i386
Much to my dismay, I rebooted after running mergemaster, and discovered that none of
my IP aliases were in place. The console indicated a "ifconfig: ioctl (SIOCAIFADDR): File exists"
for every alias entry in my rc.conf. Keep in mind these aliases were working perfectly as-is
until the upgrade (from 4.4-STABLE 9/27/01). My first few rc.conf entries:
network_interfaces="fxp0 lo0"
ifconfig_fxp0="inet 216.109.194.4 netmask 255.255.255.0"
ifconfig_fxp0_alias0="inet 216.109.194.8 netmask 255.255.255.0"
ifconfig_fxp0_alias1="inet 216.109.194.10 netmask 255.255.255.0"
ifconfig_fxp0_alias2="inet 216.109.194.21 netmask 255.255.255.0"
I was able to get homer to take the aliases by bringing fxp0 down from the console
and adding them one by one manually.. but every time I would add an alias the interface
would be put back in an "UP" state -- (is this normal??). So I would have to:
ifconfig fxp0 down
ifconfig fxp0 alias 216.109.194.8 netmask 255.255.255.0
ifconfig fxp0 down
ifconfig fxp0 alias 216.109.194.10 netmask 255.255.255.0
(and so on). If I didn't down the interface before adding an alias, I would get the above
File exists error.
Although this made ifconfig appear to have bound the IP, it really didn't. Any "alias"
IP is unreachable -- a big thanks to all of the pissed off EUs that pointed that one out to me ;-)
The "primary" IP is reachable from anywhere, though.
I've experienced this behavior on 3 of my servers...
4.4-STABLE (09/27/01) -> 4.6-PR (the box mentioned here)
4.3-STABLE (07/24/01) -> 4.6-PR
4.5-PR (02/01/02) -> 4.6-PR
I apologize if this is a known issue or my own stupidity, but it doesn't seem logical and
I'm kind of lost where to go from here. Anyone have any suggestions? Am I missing some
new kernel config option perhaps?? dmesg follows...
