Very gently, without wanting to break an existing, working setup
he asks....
Given the following Netgraph Frame Relay configuration,
are these scripts enough to create an mpd-netgraph pptp
connection throught the frame relay internet connection?
Or do I need to add some extra netgraphism's to connect into
the frame relay chain?
Proposed configuration files
mpd.links
frame-pptp:
set link type pptp
set pptp self 10.1.2.30
set pptp enable incoming
set pptp disable originate
mpd.conf
pptp1:
new -i ng0 frame-pptp frame-pptp
set iface disable on-demand
set iface enable proxy-arp
set iface idle 1800
set bundle disable multilink
set bundle authname user1
set link yes acfcomp protocomp
set link no pap chap
set link enable chap
set link keep-alive 10 60
set ipcp yes vjcomp
# require server to be .170 and remote laptop user to be .171
# as first guess
set ipcp ranges 10.1.2.170/32 10.1.2.171/32
# our dns server
set ipcp dns 10.x.y.z
# our WINS servers
set ipcp nbns 10.a.b.c 10.d.e.f
mpd.secret
user1 "pwd1"
