Need help on configuring a static internal IP address.

[Edinho]

Hello, I'm using a belkin wireless router for my home network, and I had 
DHCP enabled on the belkin routher, with this all I needed was to put 
this line on my /etc/rc.conf file:  ifconfig_fxp0="DHCP" and I was able 
to browse the internet without any problems now I decided to disable 
DHCP on my belkin router and use static IP addresses for my internal 
home network, I substituted ifconfig_fxp0="DHCP" with 
ifconfig_fxp0="inet 192.168.2.72" but I'm not able to browse the 
internet.  What else do I have to add to rc.conf?
I'm using FBSD4.8 stable, my belkin router uses 192.168.2.1, subnet mask 
is 255.255.255.0 and the gateway is also 192.168.2.1.

Here's how my rc.conf looks like now:

hostname="ecerejo.Belkin"
ifconfig_fxp0="inet 192.168.2.72"
kern_securelevel_enable="NO"
moused_enable="YES"
moused_port="/dev/psm0"
moused_flags="-z 4 5"
nfs_reserved_port_only="YES"
saver="fade"
sendmail_enable="YES"
sshd_enable="YES"
usbd_enable="YES"
linux_enable="YES"
