Added second NIC :
------------------
Our FreeBSD box was working fine with one NIC. Upon adding a second
NIC, network services didn't work. The extra NIC was detected as dmesg 
shows below :

fxp0 <Intel EtherExpress Pro 10/100B Ethernet> rev 5 int a irq 9 on pci0:16:0
fxp0: Ethernet address 00:a0:c9:e4:c2:ed
fxp1 <Intel EtherExpress Pro 10/100B Ethernet> rev 2 int a irq 15 on pci0:18:0
fxp1: Ethernet address 00:a0:c9:cf:b8:b2

I also added the following to /etc/rc.conf :

network_interfaces="fxp0 fxp1 lo0"
ifconfig_fxp0="inet 202.184.153.5  netmask 255.255.255.0"
ifconfig_fxp1="inet 10.0.0.1  netmask 255.255.255.0" 
ifconfig_lo0="inet 127.0.0.1"

But still no joy. Ifconfig showed that the interfaces were configured though.


Rebuilt the kernel :
--------------------
Figuring the kernel had to be rebuilt first for 2 NICs to work, we did :

1) rebuilt the kernel with OPTIONS IPFIREWALL enabled
2) set the following in /etc/rc.conf :
	firewall_enable="YES"
	firewall_type="OPEN"
	gateway_enable="YES"
3) /etc/rc.firewall was left as the default for "OPEN" which, if I 
   understand this correctly, should let everything through :
   $fwcmd add 100 pass all from any to any via lo0
   $fwcmd add 200 deny all from any to 127.0.0.0/8
   # Prototype setups.
   if [ "${firewall_type}" = "open" -o "${firewall_type}" = "OPEN" ]; then
         $fwcmd add 65000 pass all from any to any

This still didn't help. Again, dmesg and ifconfig report the NICs are there 
but IP services are totally dead.


Added Natd :
------------
In a vain hope that this would help, natd was also configured :

1) Added OPTIONS IPDIVERT to the kernel and rebuilt the kernel again.
2) Ensured that natd 8668/divert was in /etc/services - default anyway
3) $ natd -interface fxp0

Still no joy.

I'm guessing that something waay back at initial hardware/kernel
level is erroneous (not natd or firewall) but I can't see any conflicts
in dmesg. Any clues ?

thanking you very much,

chas

ps.  It's probably a bit overpowered for a gateway machine - but we're
     going to run Squid on it too.
