Hi,

By the looks of it you changed the IP but forgot to add the default 
route.

http://handbook.bsdjunk.com/network-routing.html

When using a static IP you're required to add in a infconfig_nic0="" and 
defaultroute="" or else it has no where to route the packets.

once you do that you can test using service netif restart && service 
routing restart
