I have set up a VPN over PPTP on a CentOS server using the DKMS module rpm dkms-0-2.0.6-3.el4 from http://centos.karan.org/el4/extras/stable/i386/RPMS/repodata/repovie w/dkms-0-2.0.6-3.el4.kb.html
and
kernel_ppp_mppe-0.0.5-2dkms.noarch.rpm at http://pptpclient.sourceforge.net/howto-fedora- core-3.phtml.
I have configured the pptpd server on Centos4 to use MS_CHAPv2, 128bit encryption and to assign server side and client IP addresses in the range a.b.c.42-48 and a.b.c.52-58 respectively.
I have also opened the firewall for tcp port 1723 and the GRE protocol (47).
I have configured a Microsoft Win2Kpro client and I can connect and establish a VPN. However I am missing something because:
1. If I try and connect to a machine on the local network segment then the VPN channel is not used (this is probably the correct behaviour but it is not what I want and I need to know how to force local network paths over an encrypted connection).
2. If I try and connect to a host outside our local network then the traffic is not routed out through the gateway but it does travel over the vpn to the local pptdp server.
So, what am I missing in all of this? Are there options for the pptpd that I need to set for this to work?
I have a similar problem when I connect from outside the local network segment. The the vpn connects but then I cannot reach any other host.
Any suggestions are welcome. I am a digest subscriber so if you could copy my email address on your reply then I would be appreciative.
