I am running my network out my ppp connection, but I am having trouble
getting the leaf machine to go through the gateway. (Yes, the system is
configured as a gateway, and the other machine, both in WFW and FreeBSD
points to it for nameservice and as a gateway. It was suggested to me to
send this information to you and see if you had any suggestions based on
it.

# Default setup. Always executed when PPP is invoked.
#
default:
set device /dev/modem
set speed 57600
disable lqr
deny lqr
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATE1Q0 OK-AT-OK \\dATDT\\T TIMEOUT 40 CONNECT"

# Example with login script
# o From PPP prompt,
# ppp> dial simplesite
# automatically dials and performs the login script.
#
# ppp> load simplesite
# loads and executes commands, but doesn't dial.
#
# o From shell, invoke as
# % ppp simplesite
# to load commands associated with the 'simplesite' label. Use,
# ppp> dial
# to establish the connection.
#
#simplesite:
# set phone 12345678
# set login "TIMEOUT 5 login:-\\r-login: ppp word: ppp ocol: ppp"
# set timeout 120

michnet:
set phone 868-6597
set login "TIMEOUT 15 host: ppp ogin: jful@dial-mich.net word: "
set timeout 60

# Multi-phone example
#
#multiphone:
# set phone 12345678:12345679:12345670:12345671
# set login "TIMEOUT 5 login:-\\r-login: ppp word: ppp ocol: ppp"

# If the peer requires to use CHAP, don't forget to supply authname
# and authkey.
#
# If you'd like to use CHAP to authenticate with the peer, comment out
# the line ``enable chap'' below. You also need to prepare /etc/ppp.secret.
#
# If the remote system sends its system name within the CHAP packet and it
# is found in /etc/ppp.secret, then the secret key is taken from that file
# and value of authkey specified here is ignored.
#
#chapsite:
# set phone 12345678
# set login "TIMEOUT 5 login:-\\r-login: ppp word: ppp"
# deny pap
# accept chap
# enable chap
# set authname MySystemName
# set authkey OurSecretKey

# Speaking PAP is like speaking CHAP
#
#papsite:
# set phone 12345678
# set login "TIMEOUT 5 login:-\\r-login: ppp word: ppp"
# deny chap
# accept pap
# enable pap
# set authname MyUserName
# set authkey MyPassword

# On demand dialup example
# Here, we assume that local side use 192.244.185.226 and
# remote side use 192.244.176.44 as their IP address.
# You must supply -auto option to invoke PPP.
#
# $ ppp -auto ondemand
#
#ondemand:
# set phone 1234567
# set login "TIMEOUT 5 login:-\\r-login: ppp word: ppp"
# set timeout 120
# set ifaddr 192.244.185.226 192.244.176.44 255.255.255.0
# add 0 0 192.244.176.44

# Another on demand example
# If the peer assigns us an arbitrary IP and we can't predict what their
# IP will be either, take a wild guess at an some IPs that you can't
# currently route to. Ensure that the "delete" and "add" lines are also
# present in ppp.linkup so that when we connect, things will be put straight.
# Note that it is illegal to use HISADDR here - HISADDR is only available
# in ppp.linkup (after the value has been established).
#
# The /0 bit says that we insist on 0 bits of the specified IP actually
# being correct, therefore, the other side can assign any IP numbers.
#
# We also set openmode active - this makes us initiate ppp negotiation.
# The default is to wait for the server to start talking.
#
pmdemand:
set phone 868-6597
set login "TIMEOUT 15 host: ppp ogin: jful@dial-mich.net word: PPP \"\""
set redial 0 0
set timeout 0
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0
delete ALL
add 0 0 10.0.0.2
set openmode active

# Examples to connect using a null-modem cable from one machine to another.
# The important thing here is to allow the lqr packets on both sides.
# Without them enabled, we can't tell if the line's dropped - there
# should always be carrier on a direct connection.
# Here, the server sends lqr's every 10 seconds and quits if three in a
# row fail.
#
# Make sure you don't have "deny lqr" in your default: on the client !
#
#direct-client:
# set dial ""
# set line /dev/cuaa0
# set sp 115200
# set timeout 900
# set debug Phase Chat LQM
# set login "TIMEOUT 5 -\\r-login:-\\r-login: ppp word: ppp HELLO"
# set ifaddr 10.0.4.2 10.0.4.1
# add 10.0.4.2 255.255.255.255 127.0.0.1

#direct-server:
# set timeout 900 10 3
# set debug Phase LQM
# set ifaddr 10.0.4.1 10.0.4.2
# add 10.0.4.1 255.255.255.255 127.0.0.1

# Example to validate incoming user with CHAP
# Invoke as ``ppp -direct users'' from login script. User's system name
# and secret-key must be registered into /etc/ppp.secret.
# IP address assigned to peer is registered in ppp.secret, then that
# value is used and value in ``ifaddr'' command has no effect.
#
#users:
# disable pap
# enable chap
# enable proxy
# set authname ppp-server
# set ifaddr 192.244.176.44 292.244.184.31

# Example of Callback Request
#
# Here, we assume that peer will hangup the line and initiates a callback
# after successful authentication. We simply use chat script capability
# and wait for a "NO CARRIER" response from our modem.
#
# $ ppp callback
#
#callback:
# set phone 0312345678
# set login "ABORT NO\\sCARRIER TIMEOUT 5 login:-\\r-login: MyName word: MySecret TIMEOUT 20 DUMMY"
# set debug phase chat
# dial
# quit

# Example for PPP/TELNET and PPP/TCP. Read doc for further details
#
#ppptelnet:
# set escape 0xff

#ppptcp:
# set device 192.244.191.33:2400

ppp.linkup
#########################################################################
#
# Example of ppp.linkup file
#
#
# This file is checked when PPP establishes a connection.
# PPP searches the labels in this file as follows:
#
# 1) The label that matches the IP number assigned to our side.
#
# 2) The label specified on the command line to ppp.
#
# 3) If no label has been found, use MYADDR if it exists.
#

#########################################################################

# If we've got 192.244.176.32 as our address, then regard peer as a gateway
# to 192.244.176.0 network.
#
#192.244.176.32:
# add 192.244.176.0 0 HISADDR

# If we are invoked with an argument ``iij-demand'', then delete all
# existing route entries and add the peer as the default gateway.
#
#iij-demand:
# delete ALL
# add 0 0 HISADDR

# Otherwise, simply add peer as default gateway.
#
#
#MYADDR:
# delete ALL
# add 0 0 HISADDR

# If we are invoked with an argument ``pmdemand'', then
# delete all existing (wrong) routing entries and add the peer IP
# as our default gateway.
# This is vital if you don't already know either sides IP number.
#
# We also want to execute a script on startup. This script can do
# nice things such as kick off "sendmail -q", "popclient my.isp" and
# "slurp -d news".
#
pmdemand:
delete ALL
add 0 0 HISADDR
! /etc/ppp/ppp.up MYADDR

The command that I use to run my ppp connection is:
/usr/sbin/ppp -ddial -alias pmdemand

questions in regard to this, do not hesitate to write. Thank you.
