how to config FBSD pc to work on non-dhcp lan

[fbsd_user]

Have FBSD gateway connected to internet with private Lan behind it.
Manually configured an MS/Windows on Lan.
Now trying to add FBSD PC to Lan.

Put ifconfig statement in rc.conf to assign PC it's Lan IP address.
Loaded resolv.conf  with IP address of ISP's DNS server.
Can ping gateway and Lan Windows box.
Gateway and Lan windows box has public access.
FBSD Lan PC can not ping Public Internet ip address or resolve
domain names.
Ping to public internet ip address get msg   sendto  no route to
host
10.0.10.0/29 is the Lan subnet. Gateway is 10.0.10.2. Windows box is
10.0.10.5.
The ifconfig display on both the gateway and FBSD lan box show the
correct
assigned IP address and broadcast ip address of 10.0.10.7 just like
what I expected.

What other config files need to be configured on the FBSD Lan PC to
get it
to communicate through the gateway to the public internet?

This is what I has so far on the FBSD Lan PC

rc.conf
clear_tmp_enable="YES"
moused_enable="YES"
moused_port="/dev/psm0"
moused_type="auto"
moused_flags="-m 2=3"

allscreens_flags="-m on -c blink -h 200"
saver="warp"
hostname="gateway.fbsdjones.com"
ifconfig_dc0="inet 10.0.10.1 netmask 255.255.255.248"

resolv.conf
nameserver 68.168.240.2

The gateway's rc.conf has
ifconfig_dc0="inet 10.0.10.2  netmask 255.255.255.248"
