Trying to setup a small local network off of my DSL. Currently I use a
different OS to do this but I am switching, or trying to..

I am using IPNAT and have added all of the options to redo the kernel.
options 	INET			#InterNETworking
options 	IPFIREWALL
options 	IPDIVERT
options 	IPFIREWALL_VERBOSE
options 	IPFIREWALL_VERBOSE_LIMIT=10
options   	IPSTEALTH
options   	TCP_RESTRICT_RST
options 	INET6			#IPv6 communications protocols

Recompiled and setup my firewall - Works great. Next went after ipnat
and natd (Note some of these I do not need I think but which ones?) I
need a clear step by step on this if someone has one. 

My RC.CONF with IP changed
# -- sysinstall generated deltas -- # Sat Nov 30 16:10:02 2002
# Created: Sat Nov 30 16:10:02 2002
# Enable network daemons for user convenience.
# Please make all changes to this file, not to /etc/defaults/rc.conf.
# This file now contains just the overrides from /etc/defaults/rc.conf.
#My ADSL router
defaultrouter="216.0.0.33"
ipfilter_enable="YES"
ipnat_anabled="YES"
natd_enable="YES"
natd_interface="fpx0"
natd_flags="-f /etc/natd.conf"
gateway_enable="YES"
hostname="myhost.myhost.us"
ifconfig_fxp0="inet 216.0.0.35  netmask 255.255.255.248"
ifconfig_xl0="inet 192.168.0.2  netmask 255.255.255.0"
inetd_enable="NO"
ipv6_enable="YES"
kern_securelevel_enable="NO"
linux_enable="YES"
nfs_reserved_port_only="YES"
sendmail_enable="YES"
sshd_enable="YES"
usbd_enable="YES"
#required for ipfw support
firewall_enable="YES"
#firewall_script="/etc/ipfw.rules"
firewall_script="/etc/rc.firewall"
firewall_type="simple"
firewall_quiet="NO"     #change to YES once happy with rules
firewall_logging_enable="YES"
#extra firewalling options
log_in_vain="YES"
tcp_restrict_rst="YES"
icmp_drop_redirect="YES"

Next added my ipnat.conf file

map fxp0 192.168.0.0/24 -> 216.222.2.35/29 portmap tcp/udp 10000:65000

So pick it apart and point me in the right direction if possible. I am
continuing to try and make it work...

Thanks

PS - This is my First post on anything in FreeBSD, the rest from MySQL
to SSHD SSL Apache PHP Webmin all went great!
