routing issue of mpd

[gahn]

Hi:

I got mpd working and logined into pptp server through
internet. From my pc, I can ping internal interface of
the pptp server, 192.168.128.1 (my pc address is
192.168.128.10). the problem is that I can't ping
anything beyond that, such as 192.168.128.2 (it
actually is an interface of a router, on the same
subnet).

>From cmd of windows, with command "ipconfig":

Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . :
254.254.254.100
        Subnet Mask . . . . . . . . . . . :
255.255.255.0
        Default Gateway . . . . . . . . . :
254.254.254.1

PPP adapter test:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . :
192.168.128.10
        Subnet Mask . . . . . . . . . . . :
255.255.255.255
        Default Gateway . . . . . . . . . :

So how could I change the length of the masking of the
ppp adapter?

once I can change the length of the masking bits, then
I can route my traffic into the rfc1918 networks that
behind of the vpn server.

the manual page of:

http://www.bretterklieber.com/mpd/doc3/mpd22.html

don't seem to be matter though.

here is the mpd.conf:

default:
        load pptp0

pptp0:
        new -i ng0 pptp0 pptp0
        set ipcp ranges 192.168.128.1/21
192.168.128.10/21
        load common

common:
        set iface disable on-demand
        set iface enable proxy-arp
        set iface idle 1800
        set iface enable tcpmssfix
        set bundle disable multilink
        set bundle enable compression
        set bundle yes crypt-reqd
        set link no pap chap
        set link enable chap-msv2
        set link keep-alive 10 60
        set link enable acfcomp protocomp
        set ipcp yes vjcomp
        set ipcp dns 192.168.64.96
        set ccp yes mppc
        set ccp yes mpp-e128

BTW, mpd4 seems to be not very stable; I switched back
to 3.18 and it works fine.

TIA
