I'm using mpd 3.2 on a freebsd 4.3 machine, ipfw with a pass any policy and
a nat. The FreeBSD machine is a firewall with an internal network of
10.0.0.0/24, internal interface 10.0.0.65.
I've got mpd configured to make the pptp connection, authentication and
negotiation works beautifully. Client is an XP machine.
I can send packets down the tunnel and can see them if I tcpdump the ng0
interface on the firewall, however I cannot get them any further than the
ng0 interface it seems.
A tcpdump of the internal interface shows absolutely no packets coming out,
not even an arp request.
The routing table on the client seems correct with a default route up the
tunnel. I can ping the internal IP of the firewall, and the firewall can
ping the tunnel ip of the client.
What am I missing? This has got to be something simple. Can someone help me
out?
The relevant config snippets are below:
mpd.conf:
default:
load pptp
pptp:
new -i ng0 pptp pptp
set iface disable on-demand
set iface enable proxy-arp
set iface idle 1800
set iface route 10.0.0.0/24
set bundle disable multilink
set link yes acfcomp protocomp
set link no pap chap
set link enable chap
set link keep-alive 10 60
set ipcp yes vjcomp
set ipcp ranges 10.0.0.65/32 10.0.0.200/32
set ipcp dns 10.0.0.65
set ipcp nbns 10.0.0.3
#
# The five lines below enable Microsoft Point-to-Point encryption
# (MPPE) using the ng_mppc(8) netgraph node type.
#
set bundle enable compression
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set ccp yes mpp-stateless
mpd.links:
pptp:
set link type pptp
set pptp self <PUBLIC IP>
set pptp enable incoming
set pptp disable originate
Any help is greatly appreciated.
