next in thread | raw e-mail | index | archive | help
I'm attempting to set up a BSD box to act as NAT and firewall on an ADSL line.
After much research and some probing of (not-very-helpful) BellSouth tech
support, this is what I've done:
1. The DHCP server upline at BellSouth has (I assume) a record of the MAC
address of the NIC they installed on the Win98 machine during the original
install. I put this card (which is xl0) in my BSD box and ran dhclient to get a
lease. I did not run ifconfig on it as I assume that the DHCP server will
take care of that. Netstat seems to show that side working fine and all Internet
apps run (fast!!).
2. I understand that dhclient manipulates some of the network config files;
/etc/hosts, /etc/resolv.conf and the routing tables. I'm still working my way
through /sbin/dhclient-script...
3. The local network (192.168.1.0) has, at present, 2 Win98s, an NT Server and
my FreeBSD box. The BSD box has been running as a gateway (troublefree) for
months using ppp -alias.
4. Ifconfig ep0 (the original NIC) shows:
flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
ether 00:50:04:12:0f:45
all of which should be correct. No change.
5. Ifconfig xl0:
flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 208.61.148.46 netmask 0xfffffe00 broadcast 208.61.149.255
ether 00:50:da:26:f4:88
media: 10baseT/UTP <half-duplex>
supported media: autoselect 100baseTX <full-duplex> 100baseTX
<half-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP
<half-duplex> 10baseT/UTP
_*I can't see the LAN*_ All three other machines can ping each other. Pinging
from the BSD box returns:

What's going on here? What stupid thing have I missed? I realize that my setup
is not complete as natd and ipfw are not configured yet, but shouldn't I be
able to see the LAN on ep0? Any help greatly appreciated. Hope I haven't
provided too much info here.
Thanks
