blocking internally

[John Lee]

hi, i have 7 ips on one box, however they can't connect internally
to each other IP ports. please advise.

here's my setup:

rc.conf:
defaultrouter="63.223.65.1"
ifconfig_sis0="inet 63.223.65.192  netmask 255.255.255.0"

/etc/ips.added:
ifconfig sis0 inet 63.223.65.193/32 alias
ifconfig sis0 inet 63.223.71.2/32 alias
ifconfig sis0 inet 63.223.71.3/32 alias
ifconfig sis0 inet 63.223.71.4/32 alias
ifconfig sis0 inet 63.223.71.5/32 alias

route add 63.223.65.193 63.223.65.1
route add 63.223.71.2 63.223.71.1
