next in thread | raw e-mail | index | archive | help
Hi,
I use mpd (Version 3.8) for a pptp vpn-connection to a customer. Now I
have some problems:
If I add "set ccp yes mpp-stateless" to the mpd.conf then the connection
doesen't work. Every time I ping a host on the other side of the tunnel
I see in the mpd.log these entries:
Sep 4 17:10:53 gateway mpd: [boehler] rec'd unexpected protocol 0x6853
on link -1, rejecting
Sep 4 17:10:54 gateway mpd: [boehler] rec'd proto 0xc43d on MP link!
(ignoring)
Sep 4 17:10:55 gateway mpd: [boehler] rec'd unexpected protocol 0x00af
on link -1, rejecting
Sep 4 17:10:56 gateway mpd: [boehler] rec'd unexpected protocol 0x3e39
on link -1, rejecting
Sep 4 17:10:57 gateway mpd: [boehler] rec'd unexpected protocol 0x761f
on link
and so on.
after I removed "set ccp yes mpp-stateless" the connection worked, but
very slow.
I saw that the mtu of the ng-interface is very low (334).
any hints?
thanx,
bye,
here are some logs (mpd, routing-table, tcpdump):
