#       MPD configuration file
#
# This file defines the configuration for mpd: what the
# bundles are, what the links are in those bundles, how
# the interface should be configured, various PPP parameters,
# etc. It contains commands just as you would type them
# in at the console. A blank line ends an entry. Lines
# starting with a "#" are comments and get completely
# ignored.

# Default configuration is "myisp"

default:
#       load PPPoE
        load vpn

#
# Mpd using PPTP for LAN to LAN VPN, always connected.
#
# Suppose you have a private Office LAN numbered 192.168.1.0/24 and another
# remote private Office LAN numbered 192.168.2.0/24, and you wanted to route
# between these two private networks using a PPTP VPN over the Internet.
#
# You run mpd on dual-homed machines on either end. Say the local machine
# has internal address 192.168.1.1 and externally visible address 1.2.3.4,
# and the remote machine has internal address 192.168.2.1 and externally
# visible address 2.3.4.5.
#
# Note: mpd does not support the peer's "inside" IP address being the same
# as its "outside" IP address. In the above example, this means that
# 192.168.2.1 != 2.3.4.5.
#
# The "inside" IP addresses are configured by "set ipcp ranges ..."
# (in mpd.conf) while the "outside" IP addreses are configured by
# "set pptp self ..." and "set pptp peer ..." (in mpd.links).
#
# See also the 'vpn' link entry in mpd.links.sample.

Hi,

OK, I think I have an MTU negotiation problem.  The server side sets an
MTU of 1458 and the client side sets an MTU of 1456.  Occassionally, the
MTUs on the client and the server will be the same and then the
connection comes up and runs like a champ as long as the MTU is 1456.
Any other values, even if they are the same on the client and server end
result in a connection that comes up and then drops.

Both the client and the server contain the line

set link mtu 1460

there is a problem with the underlaying connection, could you please post
the whole log, from the beginning of the connection.

the value of 1456 is ok, because Mpd takes the ppp-header into account,
wich has usually 4 bytes.

bye,
