What I meant by wireless vs wired ip is that after I plug in ethernet cable and trunk0 makes the em0 interface active, trunk0 still shows the IP I used with my wireless network. The dhclient doesn't renew the trunk0 from through em0 interface. If I use 'dhclient trunk0' I get new IP address but it doesn't renew the IP address automatically after connecting the ethernet cable.
