Fedora 8 VPN Client for Microsoft PPTP VPN server: routing problem

[Zvi Kave]

Hi,

Seems that the VPN PPTP connection to MS  PPTP server is OK as from the
/var/log/messages, but I can not access the required IP behind the MS 
server.
(But from Windows XP , I have no problems to connect to desired IP)

Here are the details:

1. Before starting my netstat -r

(1.1.1.0 is my local network)
Destination     Gateway         Genmask         Flags   MSS Window  irtt 
Iface
1.1.1.0         *               255.255.255.0   U         0 0          0 
eth0
192.168.122.0   *               255.255.255.0   U         0 0          0

link-local      *               255.255.0.0     U         0 0          0 
eth0
default         1.1.1.254       0.0.0.0         UG        0 0          0 
eth0

After command: pppd call vpn1
I got the following messages in /var/log/messages

I understand that it means that connection tunnel is ready.

netstat -r is now:

eth0

I need now to get connection to IP 172.25.9.64 behind the Windows VPN 
server.
I can not do it without some route commands.

I tried the suggested commands in vain:
route add -net 192.168.10.0 netmask 255.255.255.0 dev ppp0
route add -net 172.25.9.0 netmask 255.255.255.0 dev ppp0

I tried ping 172.25.9.64 but it hanged up,
and I got the message:
ping 172.25.9.64
PING 172.25.9.64 (172.25.9.64) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted


(telnet 172.25.9.64  simply hangs up)

I am looking for correct route commands to make it working.
