With my options.pptp like this:
I can successfully establish the connection between my Linux Box and XP, where the latter is the client (With compression off in the VPN PPTP setting under 'Properties').
And I yet to sort out the problem in my OS X box, I am looking for a decent PPTP client so I can do all the settings... any suggestions?
Big thanks Peter
p.s. I've kept some references below so people can sort out some of the similar questions by reading old posts.
## CHANGE TO SUIT YOUR SYSTEM
## turn pppd syslog debugging on
## change 'pptpd' to whatever you specify as your server name in chap-secrets
# Don't need this
# Tell pptpd to find local interface and put it in proxyarp mode
# This option applies if you use ppp with chapms-strip-domain patch
# These options are for use with the OpenSSL-licensed patch
# This flavor will be obsoleted ASAP.
# NB! You should also apply the ChapMS-V2 patch
mppe-40 # both 40-bits and 128-bits encryption bite eachother
# These options are for use with the BSD-licensed patch (ppp => 2.4.2)
# This is the default implementation
# These options will tell ppp to pass on these to your clients
# To use ms-dns or ms-dns in options.pptpd it must exist in /etc/resolv.conf
