The encryption, as mpd 3.2 calls it, isn't supported by windows clients. I tcpdumped a session between my pptp server and a windows client : I got : << ... 22:14:37.382601 193.190.156.147 > mirador.cediti.be: gre-proto-0x880B (gre encap) 22:14:37.383061 mirador.cediti.be > 193.190.156.147: gre-proto-0x880B (gre encap) 22:14:37.383187 193.190.156.147 > mirador.cediti.be: gre-proto-0x880B (gre encap) 22:14:37.383325 193.190.156.147 > mirador.cediti.be: gre-proto-0x880B (gre encap) 22:14:37.383667 193.190.156.147 > mirador.cediti.be: gre-proto-0x880B (gre encap) 22:14:37.383773 193.190.156.147 > mirador.cediti.be: gre-proto-0x880B (gre encap) 22:14:37.384508 mirador.cediti.be > 193.190.156.147: gre-proto-0x880B (gre encap) 22:14:37.384949 mirador.cediti.be > 193.190.156.147: gre-proto-0x880B (gre encap) ... >> Is this the proof that the communication is encrypted ? (sorry for this newbie question but I am't a guru .... not yet -:) It is surprising because on the windows client side, I set in the security option : _ Optional encryption (If I want "require encryption", the error "encryption not supported by server" occurs) _ Allow these protocols: MS-CHAP So, if I am right, MS-CHAP includes MPPE encryption even if encryption is not explicitely set; don't it ?
