Connection Termination Problems using PPTP

Hi all,

I'm using kvpnc (0.8.9)with kde 3.5.8 for quite a time now, however Cisco/IP 
Sec was the only protocoll i've used so far.

Trying to use pptp, i encountered a strange problem:
When i choose configure KVpnc->Network->Routes: "Keep default route" for the 
pptp profile everything is fine. However when i choose "Replace default 
route" the connection is terminated after 32 or 33 seconds (reproduceably)
The console gives out:(i've modified the ip address don't wonder about the 
256)

debug: Ping to 256.23.91.2 within 1 checks every 9s was ok.
debug: Ping to 256.23.91.2 within 1 checks every 9s was ok.

debug: "killall -3 pptp" was successful.

info: Connection duration was 00 hours, 00 minutes, 33 seconds

Well anyone any ideas??
How can the peer be not responding when the ping check is ok ??

Can you try the latest snapshot 
(http://download.gna.org/kvpnc/testing/snapshot/20071105/) or svn?

I guess its fixed now.

Allright I've downloaded the latest snapshot... unfortunately it doesn't solve 
the problem...

Allright here is what has happend with  (0.8.9) and what now happens with 
(0.8.9+20071105). All of the following applie to tests using a pptp 
connection:

1.Problem: Replacing the default route
-------------------------------------------------------
kvpnc 0.8.9:
When "Replace default route" is selected in "Settings: Configure 
KVpnc->Network->Routes" a pptp connection is terminated after 32 or 33 
seconds (reproduceably).
-------
kvpnc(0.8.9+20071105): same behaviour as in 0.8.9

2.Problem: Adding additional routes
-------------------------------------------------------
kvpnc 0.8.9:
Although additional routes where given in  "Settings: Configure 
KVpnc->Network->Routes", no routes where added anyway the connection worked, 

Re: Connection Termination Problems using PPTP

Hi all,

ok i now figured out what goes wrong: kvpnc does put up sensful routes 
automatically when using pptp:

That is my routing table before connecting: with .192.168.0.254 as the my 
local router:
192.168.0.0     *               255.255.255.0   U     0      0        0 wlan0
default         192.168.0.254   0.0.0.0         UG    0      0        0 wlan0
--------------------------------------------------------------------
That is the routing table after connecting to a Cisco IP SEC 
and "Replace-Route activated"
vpngw.somewhere.de 192.168.0.254 255.255.255.255 UGH   0      0        0 wlan0
192.168.0.0     *               255.255.255.0   U     0      0        0 wlan0
default         *               0.0.0.0         U     0      0        0 tun0

Allright that means everything which is not adressed to the local network is 
routed via the tunnel-interface !!!except!!! the packages which are send to 
communiacte with the vpn-gateway (of course this must be like this: how 
should the client, (my computer) communicate with the vpn-server otherwise??)
--------------------------------------------------------------------
That is the routing table after connecting using pptp:

192.168.1.2     *               255.255.255.255 UH    0      0        0 ppp0
192.168.0.0     *               255.255.255.0   U     0      0        0 wlan0
default         *               0.0.0.0         U     0      0        0 ppp0

See what goes wrong?: The first results in the client trying to communicate to 
the server via the tunnel-gateway-address (i.e. the adress the vpngateway has 
seen form within the vpn). However how should the client know where the

PPTP question - All traffic?

Hi All,

I have started using kvpnc under SUSE 10.3, and can connect to a cisco
VPN with no worries.  I have trouble with a PPTP though.  I can connect,
however then I have no privileges..  I can't ssh to machines inside the
network, and I can't access intranet.  My system administrator has said
that I need to send all traffic through the VPN, however I am at a loss
as to how to do this.

Your help would be greatly appreciated.

Thanks in advance,
Duncan

Try svn, it fixes the missing pptp route problem.

Announcement

Hello,

kvpnc supports now certificates within the original cisco client. This means:
- certificate file import
- certificate online enrollment
- certificate management (cisco store)

Thanks to rattila which had setup the cisco testbed.

Psk is supported too.

Best regards
