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 !!!!
