Hi to community.

Now, i use PPP PPTP client, it is working, but has a problems such as packets losses and spontaneous disconnections.

I want to try a Netgraf MPD5 pptp client as a solution. But cannot understand a reason of problem, got a peer authorisation error such as "Type UNKNOWN not supported"

The environment:

FreeBSD 10.3-RELEASE-p9

Code: 
 kldstat -v | grep ng_
                234 ng_socket
                225 ng_iface
                230 ng_ppp
                217 ng_netflow
                224 ng_ether
                229 ng_mppc
                223 ng_device
                222 ng_deflate
                218 ng_async
                221 ng_car
                228 ng_l2tp
                220 ng_bpf
                237 ng_vjc
                236 ng_tee
                235 ng_tcpmss
                227 ng_ksocket
                233 ng_pred1

        create link static L1 pptp
        set link action bundle B1
        #set link yes chap
        set link yes eap
        set auth authname usernsme

As you can see - has an authorisation problem " Type UNKNOWN not supported "
The system uses EAP authorisation type in both sides, and by CHAP type has a simular result.
What negotiation parameter i have to set up?

It solved, but only a reason found. The problem on the VPN server side, it works on Microsoft...... I think, MPD5 does not working with Microsoft protocols. The solution - to find some BSD VPN service. Am i right?
