PPTP connection over another PPTP connection

[Vladimir Grebenschikov]

Hi

Does anybody knows Is subject possible with mpd ?

I have tried both single mpd with two links and two mpd on different
machines - no luck.

Looks like one mpd does not allows receiving GRE packets inside its
traffic.

I see only following packets on internal link (that inside another link)

[sw] LCP: Up event
[sw] LCP: state change Starting --> Req-Sent
[sw] LCP: phase shift DEAD --> ESTABLISH
[sw] LCP: SendConfigReq #199
 ACFCOMP
 PROTOCOMP
 MRU 1500
 MAGICNUM d0599088
 MP MRRU 1600
 MP SHORTSEQ
 ENDPOINTDISC [802.1] 00 0e 35 03 82 74
[sw] LCP: SendConfigReq #200
 ACFCOMP

Also by tcpdump I see outgoing packets but didn't see incoming.

Any ideas ?
