I learn about ethfw, an utilisy which can solve my problem: 
http://www.bsdshell.net/hut_ethfw.html
But when i compile my freebsd4.7 Release kernel and restart my computer, i 
accure the following message:


Booting [kernel]...
panic: pmap_bootstrap: no local apic!
mp_lock = 00000007; cpuid = 0; lapic.id = 00000000
Uptime: 0s


Is someone can help me?
