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

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
virbr0
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

Jul 22 14:21:14 razleefs pppd[2898]: pppd 2.4.4 started by root, uid 0

Jul 22 14:21:23 razleefs pppd[2898]: secondary DNS address 192.168.0.5

I understand that it means that connection tunnel is ready.

netstat -r is now:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.10.12 * 255.255.255.255 UH 0 0 0
ppp0
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
virbr0
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

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

(telnet 172.25.9.64 simply hangs up)

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

Regards,

Zvi
