because there's IPFilter running on the box, and the rules weren't
updated to match the new IP. the ruleset should be located in /etc/ipf.rules.
edit the file, and replace all occurences of the old IP address.
then restart ipf:
# ipf -Fa -FS -f /etc/ipf.rules

looks like you have assigned the addres to the wrong interface?
