That was true with SLED 10. How about configuring a PPTP VPN to a
Windows RRAS server using NetworkManager in SLED 11?

I’ve found the solution to my post and wanted to share it with anyone
who
might be interested, or seaching the archives.
Folling the steps outlined in these two “How-To’s”, I was able to get a
SLED
10 laptop connected via PPTP VPN to a Windows RRAS server running under
ISA
Server 2004 on Windows Server 2003.
Both solutions are very similar. One adds details for configuring the
SLED
firewall to support VPN, and includes possible configuration changes to
the
/etc/ppp/peers/pptp file. In my testing I found changing configurations
in
the /etc/ppp/peers/pptp file produced negative results and I went with
using
my default file. It is also worth noting that the ‘KInternet’ utility
has
two good troubleshooting tools; ‘View Log’ and ‘View Data Rate’. Both
very
helpful in troubleshooting.
Lastly, I was stuck for quite a while troubleshooting the symptom “I
could
connect but not move packets to or from the remote network”. I had
missed a
key step - be sure and de-select the ‘Default Route’ check box. Even
when
adding a the VPN network to your routing tables you still need to
de-select
this option.
Thanks to everyone for all the help I receive from this Forum.

How is the best way to setup SLED 10 to connect to a Windows RRAS[/color]
VPN[color=green]
server? The RRAS VPN server I am wanting to connect to accepts[/color]
PPTP/MPPE[color=green]
connections.
Following the below procedure from
‘PPTP Client’[/color]
(http://pptpclient.sourceforge.net/howto-suse-100.phtml) I can connect
the[color=green]
the Windows 2003 RRAS VPN server. I receive a DHCP IP address from[/color]
the[color=green]
RRAS server, ‘ifconfig’ shows the connect and a handfull of packets[/color]
are[color=green]
passed over the VPN connection. But I can’t seem to connect to ANY[/color]
hosts[color=green]
on the VPN network. Pinging hosts of the vpn network produces a long[/color]
delay[color=green]
with no response, and eventually the ‘kinternet’ vpn connection is
dropped.
It is possible to setup a tunnel using the provided SUSE programs, or[/color]
you[color=green]
can use our method below. The way to try it as-is is to (a) in YaST2
select Network Devices then DSL, (b) add a custom provider with an
Authorization User Name that matches your PPTP server account, (c)[/color]
add a[color=green]
DSL device with PPP Mode set to Point to Point Tunneling Protocol[/color]
and[color=green]
Modem IP set to your PPTP server IP address, (d) try the connection[/color]
using[color=green]
Kinternet, and if it fails with an MPPE required warning edit the
/etc/ppp/peers/pptp file and add require-mppe.
