hi Jeff,
please show us the relevant settings in rc.conf (or the ifconfig commands you issue if you havent set these settings in rc.conf yet).
My gut feelling tells me you are setting the netmask for the aliased interfaces to the "proper" netmask (eg, 255.255.255.0) , rather than the /32 netmask aliases *ON THE SAME SUBNET AS OTHER IP ON SAME NIC* should have.
eg:
WRONG:
ifconfig_bge0="inet 192.168.1.1 netmask 255.255.255.0"
ifconfig_bge0="inet 192.168.1.2 netmask 255.255.255.0" << THIS netmask should be 255.255.255.255
Search the archives for the reasons behind this. I believe the reasons are specific to FreeBSD TCP/IP stack.
Best,
B
