I have it running fine in 2.4.3 driven off of an entry in one of the
rc.d scripts. Try to complile it after your kernel and modules are
built. (That is the way I did it).
Note: "{a}.{b}.{c}.{d}" represent specific devices behind your NAT
gateway.


Example entry:

echo -n "Starting ADSL service: "

# Load up the PPP/ATM/ADSL Module, then "dial" in
[ -z "`/sbin/lsmod | /bin/grep idt77105`"] && \
/sbin/insmod idt77105

[ -z "`/sbin/lsmod | /bin/grep nicstar`" ] && \
/sbin/insmod nicstar

/usr/sbin/pppd call adsl_service_script

# Load up some of the IP Masquerade modules
/sbin/modprobe ip_nat_ftp
/sbin/modprobe ip_conntrack_ftp
# /sbin/modprobe ip_masq_irc
# /sbin/modprobe ip_masq_quake
# /sbin/modprobe ip_masq_raudio
# /sbin/modprobe ip_masq_user
# /sbin/modprobe ip_masq_vdolive

# Set up IP Masquerade forwarding policies,
# port forwarding policies & stealth policies
/sbin/modprobe ip_tables
/usr/local/sbin/iptables -t nat -A POSTROUTING -o ppp0 -j
