If your router works like most do (and it appears that it does from the IP your 
linux box is getting), all you need to do is put this into /etc/rc.conf:

ifconfig_em0="DHCP"

(or rerun sysinstall and configure your ethernet card to do dhcp.)

# sysinstall

Choose Configure/Networking/Interfaces and set your NIC to do dhcp.
