Subject:   tun0 not showing up on 4.0-Release
Message-ID:  <393F1CDD.3F36AF1A@mailtag.com>

I'm trying to use FreeBSD 4.0 Release to build an NAT proxy for use with
my cable modem, and I can't get the tunnel driver to work.  I did this
on version 3.3 and it was a snap.

I have the following in my kernel config file:
options    IPFIREWALL
options    IPDIVERT
options    IPFIREWALL_DEFAULT_TO_ACCEPT
pseudo-device    tun
device      miibus
device      xl0
device      xl1

I have the following in my /etc/rc.conf file:
ifconfig_xl0="DHCP"
ifconfig_xl1="inet 10.2.1.2 netmask 255.255.255.0"
firewall_enable="YES"
firewall_type="OPEN"
natd_enable="YES"
natd_interface="tun0"
natd_flags="-dynamic"
gateway_enable="YES"

At bootup, I get the message "unknown interface tun0" when rc.conf is
processed, and again when rc.firewall is processed.  I've done a
"MAKEDEV tun0" repeatedly,  but I keep getting "interface tun0 does not
exist" when I try running "ifconfig tun0".

Since I'm not using IPv6 or dial-up, I tried remming out the following
in my kernel config, but with no improvement:
options    INET6
pseudo-device    sl
pseudo-device    ppp
pseudo-device    gif        4
pseudo-device    faith     1

I did notice that a lot of documentation shows the divert service as
being located on port 6668, but my /etc/services file has it at port
8668.  Is this a change or a bug?

Can anyone see what I missed?  Is there a change to the way we use the
tunnel driver in 4.0 that I need to know about?  Any help will be
appreciated.  Please respond to  huppe@mailtag.com as well as the
mailing list.

thanks a bunch,
Len Huppe
