I'm trying to establish a pptp tunnel to a Watchguard Firebox II with
mpd-netgraph.
I'm getting LCP rejects and the Firebox II is complaining about out-of-order
GRE packets but not sure if that is the cause of problems :-(
Also I think there is a problem negotiating an auth protocol. CHAP MSOFT vs
MSOFTv2?
Any ideas what is actually going wrong?
