I am a little bit concerned, however, because I also built a script ip-down.local, that should remove the arp proxy when client disconnected. Is this normal? So checking the routes I saw that my vpn was being sent out of ppp1, but I was adding the route to the network on ppp0. The firewall will block all access to the subnet except for pptp connections associated with pptp_srvr.

Hi, I'm having trouble getting pptpd & mschap-v2 to work. This potential security weakness can be eliminated when IPSec is paired with a Layer 2 protocol such as L2TP. Network layer security does not provide protection once the datagram has arrived at its destination host. For details and our forum data attribution, retention and privacy policy, see here Arch Linux HomePackagesForumsWikiBugsAURDownload Index Rules Search Register Login You are not logged in.

There is a procedure called parse_protocol in the file routines.c that discriminates the type of protocol to be filtered. PPTP seems initially to be just the path to the weakness, not the weakness itself. What is this suppose to mean? In your third attempt, everything goes to ppp0, which fails for the same reason (even your LAN traffic goes to ppp0 here, which you definitely don't want - I believe ).

For those ambitous enough, here is the diff for the routines file, copy this into a file called routines.diff and use the command patch -p0 < routines.diff from within the same This assumes that the client at is going to use as its target address for the pptp connection to pptp_srvr. For example, a datagram in transit would be vulnerable to spoofing attacks against its source or destination address. Therefore security functions must be imbedded on a per-application basis.

For example, you could use an upper layer mechanism such as Secure Sockets Layer (SSL) to encrypt upper layer data.
