You state.
"I have DSL and my ISP is AT&T, I have a static IP which means I
don't need to run PPP to connect."
That is not true for 4.9 and I have not read anything which changes
that for 5.x.
Is 5.1 an buildworld to existing system where your setup worked
previously? or install from scratch using cdrom? Explain.

Hi everyone,
I bring an old post again because I have now more information to
give this.
My post was this one :
--------------------------------------------------------------------
------------------------------------------------------------
--------------------------------------------------------------------
------------------------------------------------------------
I just setup a freebsd box with the 5.1 release to be a
gateway/firewall.
The installation was smooth and to setup the gateway/firewall with
nat a lot of sources are available on Internet.
Here is my problem, I can't connect to Internet from the Freebsd
box.
I have DSL and my ISP is AT&T, I have a static IP wich means I don't
need to run PPP to connect.
FreeBSD Internet NIC is : 12.103.21.x
When I type ifconfig my NIC looks fine, up and running :
rl0 : 12.103.21.x
For information the freebsd box contains 2 NIC's one for Internet
the other for the LAN (192.168.1.1)
If I ping myself no problem everything's fine, but I can't ping a
web address. I don't know if it is possible under unix but I use to
"ping www.yahoo.com" for example to know if it's well connected. But
the best proof is when I try to install samba my freebsd gives a
time out reaching the samba server on the web....
I have setup a firewall_type="OPEN" because i'm still testing but I
also setup natd and gateway variables in the rc.conf file to what is
needed up to majority of websites about firewall and gateways with
Freebsd.
I also rebuilt the kernel up to those websites wich was fine, and I
created a natd.conf file.
One more thing I think I didn't use the Domain variable when I set
up the NIC from sysinstall.... don't know if it's important!
Well I don't understand why it doesn't work.... The tech guy from
at&t hotline told me it's easy as setup a LAN.... "yes you're right
my LAN works fine but not Internet!" :S
Please somebody help me !!!!

And I now have those outputs and conf file to go with :
